They have the advantages of high motor power density, effective material saving, high transmission efficiency, low noise, and fast dynamic response due to their high speed, much smaller volume than ordinary motors, connection with the prime mover, elimination of the traditional reduction mechanism, and small rotational inertia of high-speed motors.
