Different Types Of Electric Motors Essay

| Jonathan Archer and Zefrem Cochrane are employees of the Rugged Trucks Company, a light truck division of Gigantic Motors Corporation.

The equivalent electrical circuit of a dc motor is shown in figure 5.2. It can be represented by a voltage source (Va) across the coil of the armature. The electrical equivalent of the armature coil can be described by an inductance (La) in series with a resistance (Ra) in series with an induced voltage (Vc) which

Electric cars are becoming popular recently, but did you know that they were around since 1800’s ? (Timeline: History of the Electric Car)

Using an electric motor, an experiment was performed to test the efficiency of the motor when the mass being lifted was increased in increments of ten grams. As the mass increased by each increment of ten grams, the motor efficiency decreased by an average of 7.439%. Our results were found by using the equation: efficiency=gain in potential differenceelectrical energy used Therefore, this inverse relationship proved mass affects the efficiency of electric motors.

TM4, the industrial partner, is a leading manufacturer and supplier of traction motors and drives for electric vehicle industry in Canada. As a drive manufacturer, they always aim to provide solution which is energy efficient with small footprint. In order to achieve this, they always look for alternative software and hardware solutions. Software modifications, which may improve the system performance in comparison to their existing drive control strategy without increasing the size of the system, are always sought after for continuous improvement of their system. In this regards, the internship is relevant to them for exploring alternative control strategies.

The purpose of the audit memo is to clarify the accounting policies and procedures used by clients and the accounting policies and procedures that should be followed. The audit memorandum also provides a clear explanation of a difference between the risk premium in discounting the free cash flow from Plant 3 and the risk premium in discounting the cash flows for the Macinaw Division and which of the appropriate discount rate for computation of goodwill impairment. The case mentioned about impairments which will be written down after the assets are tested for impairments and how

Consider vehicles as well as hustling? Verify on your own in NN. We have one of the most useful product scientific research electric motor in the course, indicating that every little thing functions the method it does reality be informed. Recorded specifications, dyno representations, furnishing lays out and also drove race sizes will certainly aid you place your understanding to make use of.

The electric motors work by electricity and magnets working together. Once the electricity gets going, the magnets take over. The magnets keep the motor going because the magnets used in motors have both positive and negative magnets on both sides. Surrounding the magnetic ends, are one positive and one negative magnet. This means that at any

Traditionally conventional aircraft uses the secondary power system of electric, pneumatic, hydraulic and mechanical power transfer system. Increasing demand of more advance electrical system in aircraft industries has refined the electronic power, fault-control actuator systems into a new level. To reinforce the technological progress of an aircraft electrical system, the concept of More Electric Aircraft (MEA) has been introduced in the electrical system of the aircraft by “replacing non electrical power in the aircraft with electricity.” (Corcau. J.I., Dinca. L., 2012)

Electric cars are becoming very popular in today’s world and are becoming more main stream. One reason for this is the need for automobiles that have a lower or a zero carbon footprint. For the majority of the history of the automobile, the propulsion system was a gas or a diesel engine that would run off of fossil fuels. The burning of fossil fuels is very hazardous to our world and also creates much toxic pollution. However, electric cars run off of electricity, which is a very clean and pollution free resource, depending on how the electricity was produced of course. In this paper we are going to examine the history of electric cars, look into modern electric car technology, and peer into the future of electric car technology to see if EVs might be the answer to dramatically reducing our global pollution.

In today’s sociality almost every aspect of life depends on the use of energy, especially in automobiles. There are about 253 million automobiles in the United States, but only about 500,000 of them are electric based. That is why I chose the topic to inform people of hydrogen powered electric cars. While, there is a large supply of fossil fuel, it is important to note that fossil fuels are a non-renewable source of energy. It is important to incorporate renewable sources of energy such as electricity in case we run out of fossil fuel. Therefore, electric powered cars should be popularized to limit the dependence on fossil fuel. There are many methods that generate electricity such as: solar, wind, hydropower, and hydrogen.

The future American commuter will undoubtedly have to transition from the use of fossil fuels to new alternatives due to the diminishing availability of the nation’s oil resources. How will America respond to this upcoming issue? It is difficult to predict which alternative fuel source America will ultimately choose, but with the premier of Nissan’s electric powered Leaf and other companies; such as Tesla Motors and Chevy, with their electric cars ready for market, the electric car may be winning the race to become the new standard for the gasoline alternative. Electric cars resolve long standing environmental issues, but it will need to maneuver around many roadblocks to become a marketable consideration for the general public. The

While many automakers continue to manufacture different types of electric automobiles, the question that needs to be answered is whether the market will fully embrace the new energy automobiles. Market forecast for the electric vehicles is expected to be approximately 13 million by the year 2020(Lewis). However, other companies forecast give a figure less than five million. The forecast has not been consistent unlike the market forecast for gasoline driven vehicles, which have proofed o double year after year. Market certainty is what matters, as manufacturers would like to produce products that do not stagnate in their stores but rather sale faster so they can maximize profit (Goldberg).

Electric motor, an electric machine works on the principle of electromagnetic induction, which transform electrical energy to mechanical energy. During motoring mode most of the electric motors operate through the interaction between motor's magnetic field and winding currents which result in generation of force within the motor. For some applications electric motors can operate in both motoring and generating or braking modes to produce electrical energy from mechanical energy. Electric motor is used as starter in large UAV’s.

During the last decade, permanent magnet synchronous motors have been used widely in the industry to replace DC motors and induction machines. The main characteristics of these motors are the low inertia, the high efficiency, power density and reliability. Due these
