Electric traction motor
Permanent Magnet Synchronous Motors or Asynchronous MotorsFull hybrid and battery electric vehicles are equipped with an electric traction motor that can drive the car on pure electric power. Permanent Magnet Synchronous Motors (PSM) and Asynchronous Motors (ASM) are the two main motor principles currently driving electric traction motors.
Both types present manufacturers with similar design challenges: how to best optimize power density and overall efficiency, since hitting those targets means the motors must endure higher operating speeds and temperatures.
