| 摘 要： | 利用英特工程仿真技术公司开发的一套电动机专用的耦合分析接口软件INTESIMETFMotor,对电动汽车所用永磁同步电动机进行电磁-热-流体三场耦合分析,将电磁-热-流体三场耦合与传统解耦简化模型的分析结果进行对比,以验证热流双向耦合的有效性.结果表明,单向耦合不能够保证温度的连续性和能量守恒,达不到真正的热平衡,因而需要进行热流双向耦合.

| Abstract: | A complete coupling analysis interface software named INTESIM-ETFMotor was developed by INTESIM (Dalian) Co. Ltd. to realize the electromagnetic thermal-fluid coupling analysis of automotive permanent magnet synchronous motor. The comparison of the results between the electromagnetic-thermal fluid coupling method and the traditional simplified decoupling method shows that a simplified decoupling model cannot guarantee the temperature continuity and energy conservation, which does not reach the true thermal equilibrium. Thus, it is necessary to conduct the bidirectional coupling analysis. |
