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.

Key words: permanent magnet synchronous motor (PMSM), cooling, electromagnetic-thermal-fluid coupling
