摘要
电动汽车驱动用铁氧体电机多用分布式定子绕组。以60 k W电动汽车驱动用电机为例,采用计算机仿真方法,研究分布绕组铁氧体电机电磁设计中极槽配合、磁钢布置对转矩能力和性能的影响,同时讨论铁氧体磁钢的不可逆退磁问题,得出能够指导工程实践的有益结论。
PMaSynRM for electric vehicles uses the distributed winding.A design scheme of a 60 kW PMaSynRM used in the electric vehicle was discussed.The effect of pole-slot combination and magnet arrangement on torque capability and performance was studied by simulation method in the electromagnetic design of the distributed-winding PMaSynRM,and the irreversible demagnetization of ferrite magnets was discussed in order to draw useful conclusions that can guide.
