The PMSMs operate with permanent magnets on the rotor and a three-phase AC supply to the stator, allowing precise control of speed and torque. Compared to induction motors, PMSMs offer higher efficiency, better power density, lower heat generation, and improved dynamic performance.

Key design considerations include magnet material selection (usually rare-earth magnets), rotor and stator geometry, cooling methods, and control algorithms. Advanced motor controllers, such as vector control or field-oriented control (FOC), enhance performance, efficiency, PMSM motor, high-efficiency electric motor, brushless synchronous motor, industrial PMSM applications, permanent magnet drive system and response. Modern PMSMs may also incorporate high-temperature magnets and compact designs for applications with space constraints.
