摘要
讨论一种新型双端励磁内置转子磁分路混合励磁电机的结构与原理。针对实心转子磁极存在转子涡流损耗严重的问题,提出转子磁极表面粘贴软磁复合材料(SMC)的组合转子结构,为进一步改善电机转子三维结构加工工艺,采用转子导磁体模块化方法。考虑软磁复合材料抗拉强度的局限性,研究碳纤维保护套下转子损耗特性,并进行转子结构强度分析,为该类新型混合励磁电机结构优化奠定了基础。
This paper introduces the topology and principle of a new hybrid excitation synchronous machine with dual-direction built-in field windings. In view of the serious problem of solid rotor eddy current loss, the combined rotor is presented and the soft magnetic composite（SMC） material is utilized on the surface of solid rotor. Furthermore, the modular method is applied to improve the processing technology of the three-dimensional rotor structure. Considering the tensile strength limitations of SMC material, carbon fiber is used to strengthen the rotor, and the rotor structure strength is analyzed. This paper lays a foundation for the optimization of the new hybrid excitation synchronous machine structure.
