摘要
盘式横向磁通电机(DTFM)因其电磁负荷相互解耦,功率密度高,轴向长度短,具有很好的应用前景。基于DTFM的原理特点以及软磁复合材料(SMC)和叠片硅钢材料(Si-Steel)两者间铁磁性能的互补性,提出SMC和Si-Steel组合(SMC-Si)铁心DTFM,以进一步提高DTFM的性能。该文首先给出SMC-Si铁心DTFM的结构原理;其次采用三维电磁场有限元方法,通过对比分析SMC-Si铁心DTFM、SMC铁心DTFM及Si-Steel铁心DTFM,验证三者间的性能差异以及SMC-Si铁心DTFM的性能优越性;然后,对SMC-Si铁心DTFM的齿槽转矩削弱进行研究;最后试制了一台SMC-Si铁心DTFM样机电机,并进行了试验研究。
The disk transverse flux permanent magnet brushless motor(DTFM)has a great potential application due to its decoupling between the electric load and the magnetic load,higher power density as well as shorter axial length.According to the principle features of the DTFM as well as complementary ferromagnetic properties of the soft magnetic composite(SMC)material and laminated silicon steel materials(Si-Steel),the SMC-Si Steel(SMC-Si)cores DTFM is presented in the paper in order to make further improvement on its performance.First,the theoretical structure of SMC-Si DTFM is introduced,and its superior performance is confirmed by comparison with its counterpart DTFMs made of Si-Steel cores and SMC cores respectively.Then the methods to weaken cogging torque of the SMC-Si cores DTFM are studied.At last,the prototyped SMC-Si cores DTFM is manufactured and tested.
