Analysis of Different Rotor Structures of Low-speed and High-torque Modular Fault-tolerant Permanent Magnet Motors
Compared with other structural fault-tolerant motors,modular fault-tolerant motors have been widely used because of their simple control methods and strong fault tolerance.In addition to changing the stator structure,the fault tolerance of motors varies greatly among different rotor structures.Based on the de-scription of a modular combined stator fault-tolerant permanent magnet motor(MCS-FTPMSM)with unequal span winding,the influence of three different rotor structures on the performance of the motor was analyzed in this paper.Three kinds of rotors were optimized based on rotor structure mathematical model and genetic al-gorithm.Under the premise of the same stator parameters,comparative analysis was carried out from the as-pects of the cogging torque,torque-angle characteristics,demagnetization,operation performance.Finally,a 3x3 modularized prototype of the stator was made for the experiment.By comparing and analyzing the test data with the finite element results,the rationality of the analysis in this paper was proved.
