The inherent efficiency of a permanent magnet motor is higher than an induction motor. Both motors use a three-phase design through fully 

A 3-phase induction motor uses current delivered in three phases in a sequence into the coils of a stator to create a rotating magnetic field. This induces an electric field in a coil or squirrel cage to drive a rotor. (IPM), high-voltage gate drivers and powerful STM32 microcontrollers needed to implement high-efficiency variable-frequency

Such a motor has high starting current (5-8 times) and low starting torque whereas, for high HP motor, the slip varies from 3-7%. Approximate efficiency of induction motor = (1 − s) So it is
