Abstract

This paper presents new cooling methods for permanent magnet synchronous machines (PMSM) with flux barriers. For a vehicle powertrain application the permanent magnet synchronous machines is a very popular choice, because of high power density, a high efficiency and the small package. However, this machine is susceptible to suffer insulations failures of coils and demagnetization of magnets under severe thermal condition. Therefore, it is important to have an efficient cooling method for the PMSM to generate high heat dissipation. The configurations of the new cooling methods are presented in this paper. Three different topologies are compared with a standard water cooling jacket configuration. A finite volume Computational Fluid Dynamic (CFD) model is applied to have a very accurate and comprehensive simulation.

利用通量屏障的新型冷却方法
提出了具有磁阻的永磁同步电机的冷却新方法。对于汽车动力系统应用,永磁同步电机是一个非常受欢迎的选择,因为高功率密度,高效率和小封装。但在高温条件下,易发生线圈绝缘失效和磁体退磁。因此,有一个有效的冷却方法,使永磁同步电机产生高散热是很重要的。本文介绍了新型冷却方法的结构。三种不同的拓扑结构与标准水冷套结构进行了比较。采用有限体积计算流体动力学(CFD)模型进行了非常精确和全面的模拟。
