摘　　要：永磁同步电动机以其高效、高功率密度等优点在车辆电驱动领域具有极大的优势。高功率密度意味着电机具有高电磁负荷和高温升的特性,加之车辆散热条件恶劣,因此电机的热分析与计算是电机设计的关键。本文以某特种车辆驱动用350 k W永磁电机为例,对该电机进行热建模与仿真分析,模拟出电机正常运行时内部温度场的分布情况,得出电机温度分布云图等,为电机的设计提供可靠依据。With high efficiency, high power density and other advantages, permanent magnet synchronous motor play an important part in the field of electric vehicle drive. The high power density means that the motor has the characteristics of high electromagnetic load and high temperature rise, and the heat condition of the vehicle is poor. Therefore, the thermal analysis and calculation of the motor is the key to the design of the motor. In this paper, by taking a special vehicle driving 350 k W permanent magnet motor as an example, the thermal modeling and simulation of the motor is carried out, the distribution of internal temperature field during the normal operation of the motor is simulated, and the temperature distribution of the motor is gotten, which provides a reliable basis for the design of motor.
