permanent magnet electric motor
High reliability.
It has strong fault tolerance and improved reliability.
High torque density.
Multi-phase motors have more control resources and higher control flexibility. The torque density can be increased by about 30% at most, or the material cost can be saved more under the same torque.
Low torque pulsation.
The torque pulsation frequency increases and the amplitude decreases. The efficiency of motor operation is also improved. The torque pulsation can be reduced by about 12%, the vibration and noise are smaller, and the efficiency is higher.
