A novel permanent magnet synchronous motor with heat pipe for electric vehicle is designed with the aim to reduce the end winding temperature. Software FLUENT is used to simulate the temperature fields. The temperature distribution profile of the winding of the permanent magnet synchronous motor with heat pipe is similar to that of the traditional permanent magnet synchronous motor. But the temperature values of the winding of the permanent magnet synchronous motor with heat pipe are lower than those of the traditional permanent magnet synchronous motor. The area of the region with relative low temperature at permanent magnet synchronous motor with heat pipe is also larger than at traditional permanent magnet synchronous motor. The highest temperature of the winding of the permanent magnet synchronous motor with heat pipe is 16.4°C lower than that of the traditional permanent magnet synchronous motor. The highest temperature and the lowest temperature of the lamination of the permanent magnet synchronous motor with heat pipe are all lower than those of the traditional permanent magnet synchronous motor. The temperatures of the two end caps of the permanent magnet synchronous motor with heat pipe are apparently higher than those of the traditional permanent magnet synchronous motor since some heat generated at the end winding is transferred to the end cap by the heat pipe. The low temperature area at the middle housing of the permanent magnet synchronous motor with heat pipe is larger than that of the traditional permanent magnet synchronous motor. The temperature discrepancy between the evaporator of the heat pipe and the end winding is about 60°C.
