An Electric Car Motors uses electrical energy which is storing in batteries or using other energy storage device. Electric cars are not running with gasoline engine, it is running with electric motor. Now, peoples are showing more interest to buy electric motor cars due to many reasons. The main reason is; when compared with gasoline-powered cars, an electric car creates less pollution and so it is considered as an environmental friendly car. Many gasoline powered cars are now getting replaced by electric cars. From outside, you won’t get any idea whether the car is powered by a gasoline engine or electric motor.

motor1The only clue you will get after driving the car, electric motor car produces less silent when compared with gasoline engine car. Controller provides power to the electric motor, where array of rechargeable batteries provides power to the controller. In general, many differences occur between an electric and gasoline cars. The structure of a gasoline engine seems to be a plumbing project, since it consists of exhaust pipes, fuel lines, and intake manifold whereas motor car looks like a wiring project.

Electric car motors and its types

Combination of the electric motor, the batteries and the motor’s controller is considered as an electric car’s heart. Car Motors gets power from the controller whereas the batteries give power to the controller. Both AC and DC motors are using in electric car. If the motor is AC motor then it would be having 3 phase AC motor with battery package of 300 volt and running at 240 volts. If it is AC motor then it would be running from 96-192 volts. Electric forklifts industries provide most of the DC motors which is using in electric cars.

A typical DC motor range will be 20,000 – 30,000 watt and controller range will be 40,000 – 60,000 watt. DC motors are having nice features, less expensive and simpler. The only DC motor limitation is building up of heat in the motor, overdriving results to motor gets heat up where it self-destructive. An AC installation uses any type of industrial 3 phase AC motor which can make motor finding with a specific shape, size or rating of power easier. AC controllers and motors are having regen feature. At the time of braking, the motor provides power back to batteries as turn in to a generator.

motor2While buying electric motors you need to consider two things one is Cost (AC motors cost high when compared with DC motors, but AC motors comes with different features) and other one is Availability (DC motors are easily available in local market when compared with AC motors). Different types of electric motors are available in market: DC Series wound electric Car Motors – it is considered as an electric car motors king and it is also the torque’s king. Permanent Magnet DC electric motors – it is the 2nd popular electric car motors; the only disadvantage in this is, it makes noisy. 3-Phase AC induction motors – it is the 3rd popular electric car motors, but cost of all types of electric motors are same
