Language is not only the problem faced by International students in the UK

In recent years, coming to the UK have became a attractive option for students who want to get further education with the higher quality. Because the UK is famous by its impressed education in the history. However, the increasing number of international students does not mean it is undemanding to study in the UK without facing any difficulty or it is much easier than before as a oversea student. In fact, there are numerous problems they have to solve for a meaningful oversea study experience.When referring to this topic, language has always been mentioned as an unavoidable issue for these students who are far away from their motherland. But language is not the only problem faced by international students in the UK. There are many difficulties such as differences in learning and homesickness. Language can be the main problem for all the international students even if the student is a native speaker of English, such as Americans, Australians and Indians.The reason is that students who come from an English-speaking country can be proficient in daily English, but it does not mean that they can skip this obstacle. For example, although most of the students have to get a high enough score in TOEFL or IELTS for being accepted by the school they want, they may still be unfamiliar with some terms for the subject they studied (Bamford, 2008). In other words, the ability of using English can be a barrier that every international student has to overcome. Otherwise, they would be trapped in their little safe zone and ended up as a person without sufficient confidence.So language can be the main problem for international students in the UK, but precisely it is definitely not the only issue. Because obviously, it is impossible to be a good international student by such a easy way. Differences in learning will also make oversea students feel confused at the beginning of their British life. As reported by David, Brian, Anne, Claire and Sinead (2006), in some cultures it is depr ecated to raise doubts about what the teachers said, which is totally different from the academic culture in the UK.For students who have got accustomed to this way of learning, critical thinking, which plays an important role in school life in the UK, can be difficult to adapt to the new study atmosphere and it needs time to get used to it. Differences between academic cultures are inevitably driving some international students into corner. Similarly, they must force themselves to make appropriate adjustments which is required for their study in the UK, or they would be stuck in a dilemma.Learning how to behave properly in a completely different environment of study can be a serious challenge for those students who get used to keep silence and take notes without thinking of its value. Homesickness is another conspicuous problem which make international students feel troubled. The main features of homesickness can be defined as the surrounding images about home in their minds, an in tense desire to go home, a sad emotion because missing home(Adrian, 1997).For most of oversea students, it is their first time to live further from home for perhaps thousands-miles away. In other words, it is reasonable that they would feel lonely without their family especially when some bad issues happened in their homeland. If these students can not get rid of homesickness, their whole life would be exposed in danger. Similarly, students who soak themselves in the bad mood of homesickness were likely to lose their faith in life and stayed unmotivated.As the result, they would be failed in their study and also make their family and friends down, which is the last achievement they want to reach in the world. In conclusion, international students in the UK have to face many problems, including but not limited to language. Besides language, difficulties in learning and homesickness also can not be ignored. There are still many problems which did not be mentioned in this essay. So it can be hard to deal with so many problems for international students in the UK. But it is also a unique opportunity for them to upgrade themselves.

However, globalization presents various threats and opportunities to IKEA while exposing its strengths and weaknesses to market competitors. The weaknesses and strengths have been analyzed through Value Chain Analysis, VRIN, PESTL, and Porters Five Forces frameworks. In fact, the internal and external environment where IKEA operates have been analyzed using these analytical tools and recommend ations have been provided. Introduction IKEA International is a global corporation that offers home accessories to all global clients. Being headquartered in Sweden, IKEA provides quality furnishings in the Europe, Africa, and Middle East markets. The company has recently set its presence in Gulf Corporate Countries such as Omar, Qatar, and Kuwait. In fact, in the United Arabs Emirates and GCC, IKEA is acknowledged for the provision of quality furnishings that cannot be assembled easily, but can be transported without problems. In fact, IKEA furnishings are evident in the City Festivals and residential places. Despite being globally recognized, Dubai constructed its first IKEA store in the fiscal 1995. However, the largest IKEA store was opened in the year 2005 in the Dubai Festival City. In the year 2011, Abu Dhabi launched the largest IKEA International store in the Island of Yas. Besides, IKEA has one store in Kuwait as well as two other stores in Saudi Arabia (Daft Vershinina, 2010). The purpose of this paper is to analyze the current business and operations of IKEA, external and internal analysis, the competitiveness of IKEA, as well as the strategies and challenges faced by IKEA. Analytical tools such as Value Chain Analysis, VRIN, PEST, and Porters Five Forces are used in the analysis of IKEA’s business and market operations.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More The Current Operations and Businesses of IKEA IKEA was first inaugurated in the fiscal 1943 in Sweden. In the 1980s, IKEA began to expand its business operations to the United States, UAE, GCC, and other parts of the European markets. These markets attracted the company due to several reasons: (1) the regions had very large customer base, (2) the local residents who had travelled considered themselves risk-takers, (3) the market was fragmented and (4) the potential customers could be identified with regions. The success of IKEA business relied on the sensitivity of the people to the product attributes regardless of the origin. If people regarded local products more than foreign products, then IKEA business would probably have been in danger (OBG, 2012). IKEA entry into the United States, UAE, and GCC markets was focused on the consumers the company perceived to be the potential customers. The firm opened its first US store along the coastline while the Dubai and Abu Dhabi stores were opened in the Dubai Festival City and Marina Mall. While going global, IKEA believed that people living along the coast and Islands were exposed to foreign products (Gillespie, Jeannet Hennessey, 2010). The reason to focus on the travelling consumers was that the company was determined to sell products with European standards. The success of such products would be uncertain in areas where consumers have no foreign experience. The success of this entry mode in the UAE, GCC , and Europe was to form the basis for establishment before expanding the business operations elsewhere. The entry mode adopted by IKEA when expanding to the European, UAE, and GCC markets occurred in form of a market-seeking investment undertaken to exploit new markets. The Swedish, GCC, and UAE markets are saturated and the markets can only offer limited growth opportunities.Advertising We will write a custom essay sample on The Strategic Management of IKEA for Furniture Company in UAE or Gulf Corporate Countries specifically for you for only $16.05 $11/page Learn More The company was motivated to this investment by the constant market growth and large market sizes of Europe, UAE, GCC, and IKEA aimed to serve the larger markets. According to Uppsala theory, after understanding the local market the company could move to the nearest market (Switzerland), then to Germany, UAE, GCC, and so on. In the Dubai and European markets, IKEA was met with great success after focusing on providing the cheapest solutions to gain competitive advantage (Walker Butler, 2010). However, the success in the European and UAE markets was not a straightforward endeavor given that established firms that had huge capitals pursued foreign investments. Although IKEA had made a good fortune in the Sweden market, moving capital from the country was a challenge. The capital controls in Sweden prohibited investing abroad with home gained capital. The UAE nevertheless, offered a favorable environment for the company to invest its capital. IKEA had to make quick profits and get a positive cash flow by adopting the foreign investments strategies. The European business was reorganized, and tighter controls were introduced. The company changed from offering European styled products to the American styled ones in the UAE, and GCC markets (OBG, 2010). IKEA Value Chain Analysis Primary Activities Inbound logistics In the UAE and GCC, IKEA has established a wide base of pro ducers and supplies responsible for manufacturing and supply of furniture parts. The extensive array of Middle East regional warehouses is integrated with an efficient management of inventory driven by the need to ensure that the right parts go to the right customer at the right time.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Storing the furniture components as a single package is a cost saving approach, as the stores need not to be as big as they might be expected for a furniture company (Gillespie, Jeannet Hennessey, 2010). Operations IKEA has continued to expand and increase its customers across all market segments including the UAE and GCC. Isaksson and Suljanovic (2006) observe that IKEA is the only firm in the UAE and GCC furniture industries that has managed to attract customers across the world without changing the original concept of management. This has been achieved through the development of unique product designs based on sacred dedication. Other operations include market and product research, which add to the competitive strength of the business. Outbound Logistics In an industry that is considered local by many people, IKEA has become global because of its comprehensive distribution network. The firm now delivers low cost, but quality furniture to major markets such as Europe, Africa, UAE , America, GCC, and Australia. Indeed, it is the only distributor in the industry to have established on a global scale. It has stores spread in Europe, North America, Asia, and recently established operation in the UAE and GCC. The low cost of distribution in the UAE and GCC is enabled through the innovative way of dealing with the logistic sourcing and retailing whereby the products are knocked down and shipped in flat boxes (Gillespie, Jeannet Hennessey, 2010), involving consumers in value addition by transporting, and assembling the furniture by themselves. Marketing and Sales IKEA marketing in Dubai, Kuwait, Saudi Arabia, and Abu Dhabi is accomplished through the renowned IKEA catalogue, which has existed for years. This marketing tool is the cornerstone in the firm’s concept and is distributed free of charge to the households within the stores’ principal market areas. The sales returns generated by IKEA increase because of the numerous customers who visit Marina Mall and Dubai Festival City stores. Every year, the company experiences an increase in the number of visitors due to the new products advertised though the catalogues. No other forces drive sales in IKEA much like the catalogue, which is reinforced by the homely environment of the stores. Services The great success of IKEA has been enabled through the homely services offered in the Dubai, UAE, Saudi Arabia, Kuwait, and Abu Dhabi stores. The stores have been likened to IKEA homes where a customer can get any household services including dining, children playing zones and instructions on how to assemble products on their own. This kind of high-level service maintains the attractiveness to and competitive advantage of the firm. IKEA External Analysis Using PESTEL Political The UAE and GCC environment where IKEA operates is politically polarized. Minimum wage policies are strictly observed to avoid infringing labor rights. However, in most nations including UK, Dubai, Abu Dhabi, and U S, the political parties ensure the business environment is stable. Foreign business policies are accommodative to all multinational corporations. For instance, the taxation policies allow foreign corporations such as IKEA to join the UAE, European, and GCC markets (SandÄ ±kcÄ ± Rice, 2011) Economical The prices charged by IKEA on its products and services are reasonable to the consumers in the UAE and GCC markets even during the economic slump. Given that most IKEA products are locally produced in Asian countries, it is advantageous for IKEA to operate in regions like Dubai, Abu Dhabi, and GCC. IKEA has the advantage to capture and grow in various Asian, Middle East, and European markets because the national incomes are high while the rates of inflation are low. Consumers are encouraged to purchase products since interest rates are low and the currencies are strong (OBG, 2008). Social In its global business operations, IKEA has upheld a just societal status. IKEA has improved it s stores in all countries such as Dubai, Kuwait, Qatar, and Abu Dhabi to suit the citizens’ lifestyles. For instance, customers can do shopping anytime because IKEA offers flexible and odd working hours (OBG, 2008). There are playing grounds for kids and restaurants for parents accompanying the kids. Technological In the UAE and GCC countries, IKEA has been able to endorse or market its services and products easily via the internet. The products dimension and detailed info are available online, and this allows clients from these regions to make purchases. IKEA also derives its strength through the online catalogue services. IKEA initially wanted clients to go to the Dubai, Kuwait, Saudi Arabia, and Abu Dhabi stores to pick up their products, but technology has now enabled the company to use computer operated lifts to deliver products to the clients (SandÄ ±kcÄ ± Rice, 2011). Analysis of the Competitive Position of IKEA Using Porter’s Five Forces The IKEA’s Co mpetitors There is extreme competition amongst the existing corporations in the international markets like the UAE and Abu Dhabi. For instance, in Dubai and Abu Dhabi, the company functions in a very competitive business environment typified by other economical furniture manufacturers. B esides, these producers are kin-run dealings that generate low overheads well known by focusing on expensive designs. Conversely, these expensive and focused designs translate to small-scale fabrication to suit the local UAE and GCC souks (OBG, 2012). The established experiences offer dissimilar opinions on product location and contributions according to inside accounts. To compete successfully, some large vendors like Furniture mall, Courts, and Nova generate inexpensive products to benefit from the economies of scale. Thus, IKEA appears to face stiff rivalry along with opponents from countries like Dubai, Kuwait, and Abu Dhabi. Furthermore, IKEA currently faces little pressure from fresh market en trants while the emergence of novel market competitors is also negligible (OBG, 2010). The Bargaining Power of Suppliers and Buyers As the local and universal furniture dealer, IKEA presents substitutable and broad choices of products and services to the UAE and GCC consumers owing to the level of competition. Thus, corporation offers strong bargaining power for the customers. The consumers pose a plausible threat of backward incorporation to the traders. However, retailers look for diverse means of improving performance in order to participate efficiently and generate profits. This can be realized through implementing deliberate work and business schemes based on the creation of market associations. The motivation aspires to construct enduring consumer affiliation and dealers devotion. Hence, this informs IKEA’s assimilation practice strategy amid consumers, retailers, and suppliers (OBG, 2010). IKEA seeks to enhance the reliability of the UAE and GCC customers in relation t o the purchasers’ power in the business. It focuses on improving the existing consumer association by scheming on how to win and secure the new-fangled customers to an enduring rapport with the corporation (OBG, 2008). The provision of excellent customer services with optimistic shopping knowledge is important. IKEA’s Threat of Substitutes The problem of searching for additional replaceable products that can do the same function requires an alternate product. However, there are hardly any replacements of furnishings for the other products in the UAE and GCC. With technical advancements, a significant part of the people, the account of organization supplying merchandise, and the mode of supplying services and products are extremely substitutable. It is realistic for the shopping judgment placed against the garments since Dubai, Kuwait, Oman, and Abu Dhabi customers would make an effort to appraise if the furniture is fit (OBG, 2012). To evaluate the aptness of purchasin g manufactured goods, it is important for the computer imaging to forget the establishment of rooms. Nonetheless, such substitutes stay put, as components of the company’s competitive advantage and online business remains underutilized. The Corporation Prospective Entrants In the provision of departmental stores, there are numerous furniture traders such as Courts and Nova as well as high-end vendor like Lorenzo in the GCC and UAE markets. In fact, a higher degree of opposition results from the diminishing levels of customers’ trustworthiness. This industry is experiencing threats from the innovative competitor entering into the big business. There is an obligation for renting store space since capital investment necessary for furnishings could be high. Hence, the competitors must source the designs and build the factories. In addition, before the market entrants could produce low cost products to rival the entrenched firms, they must capture a dominant market share (O BG, 2008). IKEA Internal VRIN Framework Analysis Valuable The strength of IKEA at present originates from unique sourcing, tightly controlled logistics, and unique design capabilities. Therefore, the firm offers products that are unique enough to give market recognition, reduce inventory, and secure sourcing for long runs. This strength has ensured that the firm leads in the industry and steadily increases the market share countries such as Dubai, Abu Dhabi, Oman, and Europe. Rare Throughout history, IKEA has been able to produce new designs and offer products next door from the Dubai and Abu Dhabi stores. IKEA is the only industry player that has been able to offer a variety of designs to the wide customer base found in the UAE and GCC nations (Isaksson Suljanovic, 2006). Inimitable As the activities of the value chain suggest, IKEA has a strong relationship with their UAE and GCC customers starting from the products offered to the services given. Many of the competitors found in the UAE and GCC markets lag behind in terms of customer loyalty and the locals only know a few that surface. IKEA enjoys global recognition in Dubai, Kuwait, Saudi Arabia, and Abu Dhabi due to its ability to offer the typical Swedish furniture taste, yet with a sense of the differing consumer needs (Walker Butler, 2010). Non-Substitutable The iconic aspect of self-assembly emphasized in IKEA is more of an imagination. The developments that have led to this achievement have taken years and whole commitment of the firm leaders. Even if, other competitors found in the UAE and GCC markets tried to imitate such an approach, they will not only invest costly in building trust with producers, but must do better than IKEA to dissolve the recognition the company has gained (Daft Vershinina, 2010). Major Strategic Issues and Challenges IKEA Should Address IKEA has various options to make sure it improves its performances in the depressing economic setting founded on environmental dynamism an d the state of the industry. The company can focus on the business operations to boost its UAE and GCC market dominance. To accommodate average regulars with minimal wages and discretionary expenditure powers, it may manufacture low priced designs. The company could invest in the research and development to fund its expenses and improve on the status of its product designs. Through employing products promotion strategies, IKEA could widen its sales and become the market leader in the UAE and GCC nations (OBG, 2008). Its present promotional campaigns are based on cultural awareness and exclusive marketing situations for every nation and globally differ across marketplaces (OBG, 2008). To convey the alternative and innovative television spots across the world, IKEA has worked with diverse advertising bureaus for more than a year. Hence, IKEA gives the UAE, Dubai, Kuwait, Saudi Arabia, and Abu Dhabi marketing agencies the liberty to discover some of the uncharted and fascinating ideas that generate additional attraction. Furthermore, the corporation has a stockpile that attracts additional clientele to the Dubai and Abu Dhabi IKEA stores. In Dubai, Kuwait, Saudi Arabia, and Abu Dhabi, the IKEA stores appear positioned and arranged in a way that one cannot leave without seeing all the available products or furniture. This strategy lures the Middle East customers to buy IKEA products. IKEA takes advantage of this in getting new personnel to help customers walk through the shop and see the commodities they need (SandÄ ±kcÄ ± Rice, 2011). The system enables the clientele to buy more furniture than what they planned to purchase. Further, the company profits from the healthy firm-supplier association and its economies of scale. The company might surpass the long-term agreements for the low cost supplies from the clientele by providing leased technological support and equipment. It should uphold brand positioning by offering low priced and quality products while pres erving the value image in the UAE, Kuwait, Abu Dhabi, and Saudi Arabia markets (OBG, 2008). The existence of differentiated merchandises in the value added phase permits IKEA to offer options for preference, transfer, and transportation of furniture. This should be the strategy in the Middle East operation, and should IKEA fail to obtain the goodwill, it may incorporate the service costs into the price of manufactured supplies. Recommendations IKEA is cautious about the societal and cultural aspects of the UAE and GCC where it operates. IKEA should provide a commission on its products and services and allow every department to make its own management decisions. In the Dubai and Abu Dhabi markets where IKEA currently functions, such preparations will ensure that assorted units can respond promptly to any state of crisis. Conversely, by focusing on the superiority and low manufactured goods overheads, IKEA should pursue the principle of reaching out to the costs conscious customers. T his can be realized via putting extra energy on its business operations and sourcing the supply chain resources to minimize the operation costs. Hence, IKEA International in Dubai, Abu Dhabi, and Oman should reduce the resource leasing to lower the operating fixed costs. This can be realized through choosing a shopping quarter in the suburban areas in the UAE and GCC while evaluating the existing guidelines. While operating in the UAE and GCC markets, IKEA should provide excellence services during sales periods and over the weekends when the clients overwhelm personnel in service. For the UAE and GCC to sanction the employees to supply more than one category of manufactured goods, they must cross-train their workforces in diverse fields. IKEA should let the deployment of workforce from other sections when a given sector faces many enquiries from the clientele. To fill up the vacant positions over the weekends, the corporation must hire more part time workers from the GCC and UAE pop ulace and train them appropriately. Thus, the usage customers’ discontent over quality services and the surge in customer enquiries over the weekend would be dealt with through this implementation. IKEA found in the UAE and GCC must also influence the clients to shop online so that it can take advantage of the accessible information technology. In fact, this can reduce the weekend tension on the available human resources. Above all, the corporation must dispose the delivery free of charge strategy to attract more clients on online shopping since its catalogue is wide-ranging and the customers should access it effortlessly. Conclusion IKEA has grown-up into a multi-million corporation from the fully-fledged family business since the year 1943. The corporation will breed new business sections and sustain the present marketplace strategy of low priced quality merchandise as it progresses into the next years. To nurture its UAE and GCC businesses, it will make sure that there is recurrent upgrading of consumer services to make them remain its business contents whilst using technical internet shopping. It has a strong prospective of increasing its business operations in UAE and other GCC markets through limiting its expenses and improving the market share. This is enhanced through its established background and the influence it has in the industry.

Media ethics - Essay Example Danger in so many ways is and continues to be one of the hazards of the trade. The advent of technology has brought forth a new media that allows for and searches for a new definition of press freedom. In this new avenue, censorship is becoming a mere obstacle that can be hurdled. This is not to say that oppressive governments cannot find their way into the loop but admit it or not, it has opened up a number of possibilities that allows for creativity. In the same way that administrations found alternative ways to deal with the issue and avert from the muckraking that is ruinous to them. The Asian region remains the front line in terms of censorship. The communist nations of China and Vietnam records the most number of jailed web radicals to date. The issue of censorship will never seem to elude the continent as oppressive governments are persistent upon their unruly implementation or lack thereof of press freedom. The World Wide Web has turned into a battlefield where journalists, guised in anonymity, can express themselves and expose subsequent governments. But in a number of times, this is not without its undue consequences entailed (Kushner, par. 1-2). The current trend, as Adam B. Kushner of Newsweek said is that, â€Å"governments dont just censor, they scare.† With the 210 million users of Internet in China, the government has long realized that it will be impossible to police all of them, and so in a last ditch effort for control, text messages have circulated that aims to jolt fear in common and oftentimes apolitical masses. This is a type of surveillance wherein authorities make it seem they are scattered all over to prevent and taunt those who desire to search for materials online. On a regular basis, China denies access to 19,000 websites that are considered threatening by the Chinese government according to a study conducted by the Harvard Law School. The study found out that the capital, Beijing, blocks

Case study - Essay Example One thing which is common among them is that they all love their jobs, even if they are apparently difficult to others. All the job profiles mentioned in the examples are apparently tough and hectic, which provides challenging situations and huge work load. They also demands extensive attention and time devotion to an employee’s work life. In general, most of the employees would face exhaustion and burn out while working in this schedule (Burke & MacDermid, 1999), but these individuals mentioned in the examples, are driven by challenge and they are motivated by high target fulfilment. All of them work in respectable and well renowned companies and in reputable positions. Although, they have very little time for personal life, and their work-life balance is reduced to a minimum, they enjoy their work life more than their personal life. These individuals are all self-motivated; they are driven by tough challenges and high achievement of success. According to Douglas, and Morris (2006), most workaholic people work for personal desire, they are rarely driven by the future outcome, rather what push es them is the need to complete their task and reach their goal. They all push themselves out of their comfort zone, to achieve what most of the people cannot. Some of the jobs allow the employees to travel all around the world, which is preferred by a workaholic employee, but is seen as a hectic scheduled job by an average one. According to Koà §oglu, Gà ¼rkan, and Aktas (2014) challenging workload is one of the factors of job satisfaction. Workload can be overwhelming to employees if it exceeds the employees’ working ability. Eventually, it causes job dissatisfaction and psychological withdrawal from the job. On the other hand, too little work load can cause job dissatisfaction too, because the employee eventually feels frustrated and their morale goes down (Koà §oglu,

The Dc Motor Speed Control Methods Engineering Essay

The Dc Motor Speed Control Methods Engineering Essay ABSTRACT This paper describes the Matlab and simulink converts into actuality of the DC motor speed control methods, namely field resistance, armature resistance control methods and armature voltage, and feedback control system for DC motor drives and this paper describes mathematical modelling, simulation of DC motor system using computer simulations Matlab and simulink, by this system response to change various parameters like system stability, disturbances, analysis and optimization of model parameters with respect to the quality of control. If simulation techniques are used for determining the control parameters a simulation model is necessary, which has to be constructed from the analytical model. INTRODUCTION DC Motor is an electrical motor and it most commonly used in an electrical device for easy to drive the instruments, steel rolling mills, electric cranes, and robotic manipulators due to precise, wide, simple, and continuous control characteristics. To control the speed of low power DC Motor rheostatic armature control method were used. The basic parts of the DC motor are- axle, rotor (armature), stator, commutator, field magnet, and brushes. In the geometry of brushes, commutator contacts, and rotor windings are arranged in such a manner so that when power is applied then polarities of the energized winding and the stator magnets are misaligned and the rotor will start to rotate until it is almost aligned with the stators field magnets. When the rotor reaches to alignment, the brushes move to next commutator contacts, and energize the next winding. There are variable types of DC Motor available in market with the good and bad qualities. Bad quality means lag in efficiency. To recover or stop this kind efficiency problem controller is introduce in the system. Brushed DC motors are most widely used in applications and its ranging from toys to push-button adjustable car seats. Brushed DC (BDC) motors are inexpensive but easy to drive. Brushed DC motors are easily available in all size and shape with the wide range from large-scale industrial models to small motors for light applications (such as 12 V DC motors). . BDC motors are most commonly used in easy to drive, with variable speed and high start-up torque applications. OBJECTIVE The Fig.1 shows the analogues electrical circuit.

Brushed DC Motor fundamentals A Brushed DC Motor consists of stationary fixed permanent magnets i.e. stator, a rotating electromagnetic i.e. rotor and flux, which is concentrated by metal. Rotor rotate by the attraction of the opposite poles and repulsion of the like poles, it cause to generate torque and torque acts on rotor and then make it turn. As the rotor start to rotate or turn then fixed brushes make and breaks the contact in such a way that with the rotating segments (commutation). The rotor coil of the brushed motor energized and de-energized in such a way so that the rotor start to turns. By transferring the power to the motor, current generate in rotor coils and therefore the north and south poles are reversed and because of the motor change the direction. From the Strength of the magnetic field, speed and torque of the motor depend Figure (1) Brushed DC Motor PRINCIPLE OPERATION Construction and operation of the Brushed DC Motor is shown below in figure (2).for the construction of the BDC motor always the same components are required i.e. Stator, rotor, commutator and brush. Figure (2) Simple two-pole brushed DC Motor Stator The rotor surrounded by the stationary magnetic field which is generated by the stator and this filed is generated by the permanent magnet or electromagnetic winding. On the construction of the stator, different types of BDC distinguish. Rotor Rotor is also known as an armature and it is made up of one or more windings. Magnetic field is produce when they energized. When the opposite pole of the magnetic poles, attract to each other which is generated by the stator, and causing the rotor to turns. The opposite poles are always attracting to each other. As the motor turns, the windings are being constantly energized. This deviation of the field in the rotor is called as an armature. Brushes and commutator There is no requirement of controller in BDC to switch current in motor winding. The commutation winding of the BDC motor is done mechanically. Reside on the axel of rotor there is a segmented copper sleeves called commutator. Carbon brushes slides over the commutator coming in a contact with the different segments of the commutator as the motor starts to turn. When the voltage is applied across the brushes of the motor then dynamic magnetic field is generated inside the motor. Brushes and commutator are the most important parts of the BDC motor that are most prone to wear because they are the sliding part to each other. SPEED CONTROL The Speed of a DC Motor is directly proportional to the voltage. By using the digital controller voltage can be control and to generate the average voltage pulse-width modulated (PWM) signal is used. In motor there is a motor winding which acts as a low pass filter so PWM develop a suitable current in the motor winding. ADVANTAGES Cheap in price because low cost of construction. Extend a life by replacing a brush. Inexpensive motor and simple control. Speed/Torque is normal at high speed. On fixed speed no control is required, Controller is required only at variable speed in this condition same controller can be used. DISADVANTAGES Maintenance is required for brushed DC Motor because of brush. If the brush friction increases, reduce the useful torque. Heat dissipation is poor because of internal rotor construction. Speed range is limited because of the mechanical limitation on brushes. Life is also shorter. Noise is generated due to brush. Application examples: moving toys, fans, printers, robots, electric bikes, -doors, -windows, -sun roofs, -seats, mixers, food processors, can openers, blenders, vacuum cleaners, toothbrushes, razors, coffee grinders, etc. Physical Parameters Moment of inertia of the motor (J) = 9.89 E-7 kg Nm s/rad Damping ratio of the mechanical system (b) = 5.84E-7 Nm s/rad Electromotive force or motor constant (K=Ke=Kt) = 0.008 Nm/-w Electric resistance (R) = 0.80 ohms Electric inductance (L) = 0.00041H Friction coefficient, f Input (V): Source Voltage Output (theta): position of shaft the rotor and shaft are assumed to be rigid CONCLUSION Brushed DC motors are very simple to use and easy to control, which makes them a short design-in item. PIC microcontrollers, especially those with CCP or ECCP modules are ideally suited for driving BDC motors. Refference Circuit Diagram for DC Motor Control by A.
