| 摘 要： | 本文研究了三种不同退磁方式对永磁游标电机的电磁性能的影响，建立了永磁游标电机的退磁解析模型。该解析模型建立在精确保角映射的基础上，能准确地反映永磁游标电机的有槽气隙与无槽气隙之间的关系，从而准确计算磁场分布。针对永磁游标电机的退磁分析中存在的问题，提出了退磁电流与退磁永磁体之间的等效变换，在此基础上通过完全保角映射后得到准确的退磁磁场分布。最后采用有限元分析验证了永磁游标电机退磁解析模型。

| Abstract: | This paper investigated the demagnetization of permanent-magnet vernier machine based on analytical models.Three kinds of demagnetization were considered to show its influence on the electromagnetic performance.Therefore,the characteristic of demagnetization for permanent-magnet vernier machine can be analytically obtained.The analytical model was based on the exact conformal mapping,which can exactly show the relationship between slotted and slotless air-gap of permanent-magnet vernier machine.The equivalent transformation between demagnetize PM and dot current was proposed to make sure that the exact conformal mapping was suitable for the electromagnetic analysis of permanent-magnet vernier machine.Finally,the high accuracy under demagnetization condition was validated by finite element analysis. |
