| 英文摘要: |
| In order to improve the output torque and speed, and reduce the permanent magnet (PM) eddy loss for magnetic gear, a novel
magnetic gear with stationary PM ring is proposed. The operating principle and torque performance are analyzed, and the results showed
that the novel magnetic gear has high efficiency, high torque density and high speed compared with traditional magnetic gear. Taking
high output torque and low cogging torque as the optimization goals, a multi-objective optimization method based on the parameter
sensitivity and response surface method is introduced, which aims to accurately obtain the magnetic gear structure parameters. Then, the
PM ring, outer rotor and inner rotor are optimized. By analyzing the electromagnetic performances for novel magnetic gear between initial
and optimal magnetic gear, the results show that the output torque is improved, and it lays a foundation for its application and
optimization design. |
