Permanent Magnet Synchronous Motor  Favorite


Overview

The Permanent Magnet Synchronous motor is a rotating electric machine where the stator is a classic three-phase stator like that of an induction motor and the rotor has permanent magnets.

The use of a permanent magnet to generate a substantial air gap magnetic flux makes it possible to design highly efficient PM motors.

Key Features

  • Medium construction complexity, multiple fields, delicate magnets
  • High reliability (no brush wear), even at very high achievable speeds
  • High efficiency
  • Low EMI
  • Driven by multi-phase inverter controllers
  • Sensorless speed control possible
  • Higher total system cost than for DC motors
  • Smooth rotation without torque ripple
  • Appropriate for position control
