车用永磁同步电机三维温度场分析
Analysis on Three-dimensional Temperature Field of Permanent Magnet Synchronous Motor in Vehicles
摘要
Abstract
In order to study temperature field of PMSM used in vehicles,a rated power of 25 kW PMSM in vehicles was taken as the research obj ect,and its three-dimensional solution domain model was built based on the basic theory ofheat transfer.The motor's steady state condition temperature field and the temperature rise changes were derived through simulation analysis.Also,the simulation analysis on temperature rise of the key parts in the motor was carried out under continuous variable power working conditions,for the sake of studying the changes in motor temperature field under actu-al driving conditions of the vehicle.By building an experimental platform,the effective tests of motor's temperature rise were carried out under rated operating conditions and continuous variable working conditions.By contrast and analysis,experimental data are close to simulation data,which verifies the accuracy of the simulation.关键词
