| 摘 要： | 提出了一种适用于电动汽车驱动系统的E型铁心混合励磁轴向磁场磁通切换型永磁(HEAFFSPM)电机。以一台三相6/10极电机为例,基于三维有限元方法全面研究该电机静态特性,包括气隙磁密、空载永磁磁链、空载反电动势、电磁转矩、转矩-电流特性、绕组电感和磁场调节能力等；研究转子齿扇形角度和转子斜极对电机反电动势和齿槽转矩的影响,分析表明转子齿扇形和转子斜极可以改善反电动势和齿槽转矩波形。制造了一台2 kW样机并对其进行测试,验证了有限元分析结果的准确性,结果表明HEAFFSPM电机的磁链和反电动势均为正弦分布,带载能力和磁场调节能力均较强。

| Abstract: | An ecore hybrid excited axial field fluxswitching permanent magnet (HEAFFSPM) machine, which was suitable for electrical vehicle drive, was developed. The electromagnetic performances of a 3phase 6/10 stator/rotorpole HEAFFSPM machine, including the airgap flux density, the PM flux linkage, the back electromotive force (backEMF), the electromagnetic torque, the torquecurrent characteristics, the winding inductances, and the field regulation capacity, were thoroughly investigated based on 3D finite element method (FEM). The influences of the rotor pole shape angle and rotor pole skewing on the backEMF and cogging torque were analyzed. It showed that the backEMF could be improved and the cogging torque could be reduced with trapezoidal rotor pole shape and skewed rotor pole. A 2 kW prototype was built and tested, which validated the FEM analysis. Results showed that the HEAFFSPM machine exhibits the essentially sinusoidal phase flux linkage and backEMF, good loadcarrying capacity and flexible fluxregulation capacity. |
