Electrical Energy Into Mechanical Energy

He’s astounding invention was the induction motor. According to webster-mirriam dictionary, an induction motor is “an alternating-current motor in which torque is produced by the reaction between a varying magnetic field generated in the stator and the current induced in the coils of the rotor”. The invention of this machine has revolutionized the machine industry. It was used to generate power from Niagara Falls, this motor has improved the generation and distribution of electricity. In addition, the induction motor was also used to run the famous Tesla Model S due to its efficient design. As a result, Tesla became one of the most famous inventors around the

As well as the cost, the convenience of fuel (gas) powered cars is far greater than that of electric powered cars. For an electric car people must be able to find an electric outlet in order to charge the car. Meaning the car must be kept in the garage for charging. Another disadvantage of electric powered cars is the ability to receive a charge while on a long trip. When people are traveling far distances, they often need to refuel at a gas station, but with electric car there are not as many gas stations with the option of recharging a car. Therefore, making the electric powered car less

Electric vehicles (EV) are one of the cleanest and most environmentally friendly cars available at this point in time. By definition, an electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable or another energy storage device. The electric motors used in these cars gives off instant torque, creating strong and smooth acceleration. Some of the models of EVs have an electric motor for each wheel. Having these four motors not only allows for better propulsion, but also for the use of braking and changing the kinetic energy back into chemical energy in the batteries. The traction that the car gets is also increased with each wheel driving. In some of the EV models the electric motors can be mounted directly inside the mounting for the wheel, which enables a loss of all the moving parts between the motor and the wheel. When there is no axle, differential, or transmission, the EVs have less drivetrain

Looking around, you may notice the sudden surge of sustainable engineering all around you. From new LED light bulbs, to many different kinds of robots this epidemic is sweeping the world more and more. While we are slowly shifting towards new technologies, there is one that has gained extreme popularity over the past couple of years. It is electric cars. Going a few years back to 2010 there were a few companies introducing their first models of electric cars, but almost no one was interested in buying them, and some people even hated the idea of driving one. Since then many aspects have changed and electromobility has become one of the most debated topics in car industry. So what are advantages and disadvantages and why are they so popular now?

One significant innovation was the engine that was created in 1712 by Thomas Newcomen. It was, first created to be used in navigation and succeeding to power machinery which revolutionized the world and started the industrial era. The engine acts as a powerhouse making machines move, but needs fuel to keep it running. Mechanical Engineers are assigned to learn the functions of the engine itself and understand how to further improve it by making it reduce the consumption of fuel or to increase the power output. Unlike automobiles, ships and airplanes with their size, still need lots of fuel due to tremendous power needed to be able to move. Cars that run using electricity do not handle gas for fuel, making it eco-friendly, however they do not provide as much power as the cars that run with gas.

The first fundamental part needed in an electric vehicle is the electric motor. To put it simply, the job of the electric motor is to propel the car. Unlike a typical combustion engine, which has hundreds of moving parts, an electric motor only has one moving part [4]. The positives of this include a much lower initial cost compared to a fossil-fuel engine with the same horsepower. Having fewer moving parts also means that the motor has a longer lifespan.

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.

Electric cars possess less moving parts; for this reason, they have fewer maintenance requirements and expenses. Without a doubt;

What is efficiency? According to Farrell efficiency is production of maximum amount of outputs from given amount of input or alternatively minimum input quantities producing a given amount of output (Farrell, M.J.

The first production electric cars were produced around the early 1900s and they were tremendously more popular than cars with gasoline engines. They eventually died out in the 1920s because of the decrease in cost of the gasoline engine. Even though electric cars faded away in the 1920’s they are making a comeback now due to the many benefits of an electric car over the traditional gasoline engine. Because of the rapid evolution of the electric car raises concern on the future of the gasoline engine, also the rise in popularity of the electric car because of environmental and other reasons. The future of electric cars will negatively affect the longevity of the gasoline engine because of the advancement of technology (or the area of) in

Some people think that electric cars are great on power but in reality they are not great on power. According to Alternative Fuel Vehicles hybrids smaller are internal combustion engines and lighter weight help maximize efficiency, but can reduce acceleration.

Despite the numerous benefits that are associated with electric cars, there are some drawbacks that have prevented the popular use of the cars in the current period. Among the drawbacks is the high cost that is associated with buying an electric car. According to Jager et al. most of the electric cars in the market are

When it comes to electric lawn mowers, there are many people who choose this type of machines due to the fact that they are a lot cheaper than other models. Furthermore, they only require little maintenance, which is another great advantage of owning a device like this. A quick start is also provided. This type of lawn mowers are a lot more practical that other types, and they are also very easy to use. Due to the fact

In today’s motorized life , It’s difficult to live without motor (Engines) and the main source of it’s input power is fossil fuels & partly electric power. In future these fuels or electricity may not be available widely as they are non renewable energies. So, it may be difficult to use engine with the fuels.

In an inner rotor style, the stator coil windings surround the rotor and are mounted to the motor's housing as shown here. The first advantage of an inner rotor construction is its ability to dissipate heat. A motor's ability to dissipate heat directly impacts its ability to provide force. For this reason, the overwhelming majority of BLDC motors use an inner rotor style. Another advantage of an inner rotor style is lower rotor inertia.
