What's the Permanent Magnet Synchronous Motor( PMSM)?

Permanent Magnet Synchronous Motor( PMSM) is a synchronous motor whose field excitation is provided by permanent magnets, and has a sinusoidal Back EMF waveform.

  • With permanent magnets the PMSM can generate torque at zero speed

  • Higher torque density versus AC Induction Motors (ACIM), i.e., smaller frame size for same power

  • High efficiency operation

  • Requires digitally controlled inverter for operations
