摘要
以一台额定功率为25 k W的纯电动汽车用永磁同步电机为研究对象,利用集中参数法建立了电机的热网络模型,通过建立其热平衡方程组,计算电机内各零部件的节点温度;同时基于有限体积法,建立了电机的求解域模型,利用Fluent软件计算电机的温度场,并同热网络法求解进行比较。借助于实验平台,对计算结果和实验结果进行对比分析,以验证利用热网络法和有限体积法求解电机温度场的准确性。
A rated power of 25 kW PMSM in pure electric vehicles was taken as the research object, lumped parameter method was used to establish a thermal network model of the motor, and the junction temperatures of each parts of the motor were calculated by establishing its thermal equilibrium equations. Meanwhile, the solving domain model of the motor was established by the finite volume method. Fluent software was used to calculate the temperature field of the motor, and the results were compared with the thermal network solution. The calculation results and experimental results were analyzed by means of the experimental platform to verify the use of the thermal network method and finite volume method for solving the accuracy of the motor temperature field.
