Let me put it this way – The Tesla uses this type of motor. AC induction motors are the best because they use the battery the most effeciently (giving you more range), they do not wear out the original transmission of the vehicle they are mounted to and the transfer of power is easier to manage than a DC motor, and they can be used with bigger cars and heavier loads than a DC motor. Because of this, this is the ONLY engine I would recommend that anyone considers when they are building an electric car. They cost more than the other two, but they are highly worth it in the long-run for performance.
This motor is configured differently than the DC motors used to power an electric car. Instead of a controller unit for the DC engine, this replaces the controller with a DC-AC inverter installed in the car. So you have to purchase more electrical parts required to turn your gas car into an AC electric powered car than with a DC motor.
