AC Induction Motors vs. Permanent Magnet Synchronous ...

A "PMSM", which stands for "permanent magnet synchronous motor", relies on magnets to turn the rotor, which spins at the same speed as the PMSM's internal rotating magnetic field. There are a few key differences between AC induction Motors and Permanent Magnet Synchronous Motors. Permanent magnet motors MUST operate with a drive.

Permanent magnet motor - Wikipedia

A permanent magnet motor is a type of brushless electric motor that uses permanent magnets rather than winding in the field.. This type of motor is used in the Tesla Model 3, the Chevy Bolt, and the Chevy Volt.. Permanent magnet motors are more efficient than traditional induction motors or motors with field windings for certain high-efficiency applications such as electric vehicles.
