为了分析ISG电机在混合动力汽车不同工作模式下的工作状态、发热情况以及冷却风速对电机温度场的影响,建立了ISG电机整体结构三维模型,给出了ISG电机边界条件,运用COMSOL软件在电机额定状态和峰值状态下对电机三维瞬态温度场进行了仿真计算,将仿真结果与电机温度试验数据进行对比,并在电机额定状态下对不同冷却风速下电机温度场进行了仿真计算。研究结果表明:电机最高温度出现在电机定子线圈上面;仿真数据和试验数据的一致性验证了该模型及其仿真计算方法的正确性;冷却风速对ISG电机温度场分布趋势影响不大,对ISG电机最高温度影响较大。
In order to analyze the influence of ISG motor working condition, heating condition and cooling wind speed on the temperature field of hybrid electric vehicle under different working modes, a three-dimensional model of ISG motor’s overall structure is established. The ISG motor boundary conditions are given. Using COMSOL software, The three-dimensional transient temperature field of the motor was simulated under the condition of rated state and peak state. The simulation results were compared with the experimental data of the motor temperature. The motor temperature field under different cooling wind speeds was simulated under the rated state of the motor. The results show that the maximum temperature of the motor appears on the stator coil of the motor. The consistency between the simulation data and the experimental data proves the correctness of the model and the simulation method. The cooling wind speed has little effect on the temperature distribution of the ISG motor. Motor maximum temperature greater impact.
