摘要

本文介绍了为高功率密度永磁电机创建冷却系统所面临的挑战。为了提高定子的冷却性能，提出了一种空气/水混合冷却系统。首先采用有限元法计算定子绕组损耗，包括趋肤效应和接近效应。通过CFD模拟，讨论了气流速度、气流湍流度和液体速度的影响，找到了最佳工作点。对混合冷却系统的性能进行了评价，并提出了设计建议。

HYBRID COOLING DESIGN OF PERMANENT MAGNET SYNCHRONOUS MACHINES

This paper presents the challenges of creating a cooling system for a permanent magnet machine with high power density. A hybrid air/water cooling system is presented with the aim of enhancing the cooling performance of the stator. Finite element calculations are first used to determine the winding loss in the stator, including skin and proximity effect. The effect of air speed, turbulence of the air flow and liquid speed have been discussed to find the best working point, using CFD simulation. The performance of the hybrid cooling system has been evaluated and design recommendations established.
