摘要:
为了满足机械强度要求,高速永磁电机通常采用径向磁通结构。随着非晶合金等新型超薄 软磁材料的发展,高速高频轴向磁通永磁电机逐步引起关注。为此,针对一种适合于高速运行的磁 极分段式轴向磁通永磁电机转子结构进行研究。建立了该转子结构强度解析计算模型,分别利用 解析法和有限元法计算了不同极弧因数、转子轮缘宽度以及转子磁极分段数对转子机械强度的影 响规律。同时研究了磁极分段式结构对轴向磁通永磁电机气隙磁密、空载反电动势、齿槽转矩和转 矩密度等电磁性能的影响。结果证明采用磁极分段式结构能有效提高转子强度,相关研究工作为 高速轴向磁通永磁电机的设计提供参考。
Abstract:
In order to meet the requirements of mechanical strength,radial flux structure is always adopt-ed in high-speed permanent magnet motor. With the development of ultra-thin soft magnetic materials, such as amorphous alloy,high-speed high-frequency permanent magnet motor with axial flux structure is drawing more and more concern. Therefore,a kind of axial flux permanent magnet motor ( AFPMM) with segmented rotor pole structure that is suitable for high-speed operation was studied. An analytical model was built to evaluate the mechanical strength of this type of rotor. Both analytical method and finite ele-ment method were used to study the influence law of rotor strength under different pole arc factors,flange width of rotor,and number of segments of each rotor pole. Meanwhile,the influence law of segmented ro-tor pole structure on the electromagnetic performances of AFPMM,such as air gap flux density,no-load back EMF,cogging torque and torque density was studied. The research work provides a reference for the development of high-speed AFPMM.
