Like a multiphase AC motor, but contains magnets at rotor
Medium construction complexity, multiple fields, delicate magnets
High reliability (no brush wear), even at very high achievable speeds.
1. High efficiency.
2. Low EMI.
3. Constant output speed.
4. Sensorless speed control possible.
5. Smooth rotation- without torque ripple.
6. Appropriate for position control.
