摘要
轮毂电机作为未来电动汽车的最终驱动形式,电机性能直接决定电动汽车的安全可靠性。以一台2k W的车站巡逻车用直驱外转子无刷电机为研究对象,首先建立电机的三维温度场模型,确定电机导热系数和散热系数,然后利用ANSYS-Workbench中的热稳态模块计算了电机的三维温度场,得到电机温升特性,最后搭建实验平台进行测试,验证了仿真的可靠性。
The performance of the wheel hub motor which is the final drive method of future electric cars directly determines the safe reliability of the electric ear. A direct-drive outer rotor BLDC of a patrol car with 2 kW power was introclucect as the research object to analyze the performance of the motor. The 3D temperature model of the motor was established, and determined the coefficients of thermal conductivity and heat transfer, and then calculated the 3D temperature field using the thermal steady module in the ANSYS-Workbench software, and finally obtained the temperature rise characteristics of the motor. At last, by establishing experiment platform, the reliability of the simulation was verified.
