摘要
为研究永磁力矩电机的温度场,考虑电机各部件比热容、导热系数、动力黏度、流体边界条件、对流换热系数的影响,建立永磁力矩电机的热阻网络模型和流固耦合模型,对永磁力矩电机进行瞬态温度场仿真分析。将基于两种模型所得的热计算结果进行对比,并建立样机温升试验平台开展温度试验。试验结果表明,两种模型的温度变化趋势与试验结果接近,偏差在5%以内,由此验证两种模型的精确度与正确性,为永磁力矩电机的温度场研究提供了方法。
In order to study the temperature field of the permanent magnet torque motor,considering the effects of specific heat capacity,thermal conductivity,dynamic viscosity,fluid boundary condition and convective heat transfer coefficient of each motor component,the thermal resistance network model and fluid-structure coupling model of the permanent magnet torque motor were established,and the transient temperature field simulation analysis of the permanent magnet torque motor was carried out.The thermal calculation results obtained based on the two models were compared,and the prototype temperature rise test platform was established to carry out the temperature test.The experimental results show that the temperature change trend of the two models is close to the test results,and the deviation is within 5%,which verifies the accuracy and correctness of the two models,and provides a method for the temperature field study of permanent magnet torque motor.
