| Abstract: | A Spoke array permanent magnet vernier fault-tolerant machine with alternate flux bridges was proposed.Fault-tolerant tooth was used to improve the fault-tolerance performance.Firstly,the structure of SAPMVFM was proposed.The alternate flux bridges have been introduced to improve the magnetic circuit of the high pole ratio SAPMVM and increase the output torque.Halbach array on the stator was used to improve the output torque fluctuation caused by the flux bridges.Secondly,the electromagnetic principle of vernier motor and operating principle of flux bridge were analyzed.Thirdly,the structure of the motor was optimized to better back EMF and output torque.At last,the performance of three different motors was compared by the finite element simulation,and the improvement of the flux bridges and Halbach array on the spoke array permanent magnet vernier fault-tolerant motor was verified. |
