摘要

本文主要研究了永磁同步电动机的瞬态热模型和定子片肋部气流冷却模型。定子层压具有新的专门设计的形状。这种类型的层压不需要框架，层压是直接冷却的。它降低了冷却介质与定子片之间的热阻。热模型加载可变功率，冷却空气的气流速度是可变的。采用ANSYS CFX和Mechanical软件对热模型进行求解。永磁同步电机的热模型是基于牵引电机的。这台机器是封闭式设计的。建模的永磁同步电机用于电动赛车公式。

Coupled Transient Thermal Analyses of Passive Cooling Traction PMSM from the Racing Formula

This paper is focused on the transient thermal model of the Permanent Magnet Synchronous Motor (PMSM) and the airflow cooling model through the ribs in the stator lamination. The stator lamination has a new specialized designed shape. This type of lamination does not need a frame, and the lamination is directly cooled. It has reduced the thermal resistance between the cooling medium and stator lamination. The thermal model is loaded with variable Power, and the airflow speed of cooling air is variable. Thermal models are solved by software ANSYS CFX and Mechanical. The thermal model of PMSM is based on the traction motor. This machine is designed as enclosed. The modelled PMSM is used in the electric racing formula.
