Electric Motor / Generator
The engine is the electric drive in the electric vehicle.
Modern electric vehicles use brushless AC motors, which means that, unlike brush motors, there is no direct electrical contact between the moving rotor and the fixed stator. As a result, it has less friction and a longer endurance.
The electric motor can also act as a generator and be used to charge the accumulator (recuperation): during braking, the kinetic energy is recovered and fed into the battery.
