Abstract:

Compared with NdFeB permanent magnet synchronous motor, the amount of permanent magnets in NdFeB permanent magnet reluctance synchronous motor is significantly reduced and has a price advantage at the same performance. Compared with ferrite permanent magnet assisted reluctance synchronous motor, the manufacturing cost of rotor core with NdFeB permanent magnet synchronous motor is relatively low and the reliability of the machine was improved. Two typical rotor structures of NdFeB permanent magnet assisted synchronous reluctance motor were analyzed. The influences of rotor structure parameters on the performance of the motor and the torque capability were discussed, and the results were compared with that of the NdFeB permanent magnet synchronous motor. The simulation results show that the utilization ration of reluctance torque of NdFeB permanent magnet reluctance synchronous motor is increased, the amount of magnet steel is reduced, and the performance-price ratio of the motor is improved.
