【摘要】 为了提升新能源车用驱动电机的功率密度,各大电机厂商都在不断地提升电机转速,随之而来的问题就是电机的铁耗也在不断增高,如何降低电机铁耗成为了电机厂商必须要解决的难题。本文讨论了电机铁耗的组成部分及影响因素,并对1台8极48槽的永磁同步电机分别使用3种不同厚度的材料进行仿真,对比其效率及铁耗分布,推导出驱动电机中硅钢厚度、铁耗及成本的关系,最后对驱动电机选材提出建议。
【Abstract】 In order to increase the power density of traction motor for new energy vehicles,major motor manufacturers have been constantly increasing the motor speed.The following problem that manufacturers have to solve is how to reduce the increasing iron loss when the motor speed is increased.The components and influencing factors of motors’ iron loss were discussed in this paper,and an 8-pole 48-slot permanent magnet synchronous motor using three different thickness materials was simulated.To compare i…
