A permanent magnet motor is a synchronous motor. Its rotor, equipped with permanent magnets, is driven by the stator's electromagnets. Such motors are piloted by special electronics.
These motors can be used for propulsion (elevators, trains, electric vehicles, etc.). They also are used in dentistry to drive tools at very high speeds. Stepper motors use such technology for positioning operations.
Such motors are brushless. Stator windings are excited by a variator, which determines frequency and the command signal phase. Hall-effect sensors indicate rotor position. Some advanced variators use absorbed current analysis (degraded mode) instead of sensors.
These motors offer excellent output and half as much loss as asynchronous motors. Though expensive, they are comparatively lighter and faster. Peripherally-positioned rotors allow them to be used as wheel motors. Braking energy can be recovered.
Power permanent magnet motors are three-phase. The rotor features three poles, but control remains via commutation electronics. Stepper motors can feature an even greater number of poles to ensure precise positioning.
Choice will depend on the load to be driven. Consider the motor's power and maximum rotation speed.
- Excellent output
- Position and speed control
- Requires a frequency variator
