EV 구동용 IPMSM의 도체 개수에 따른 교류 동손 특성 비교 분석

In this paper, the research on the AC copper loss of Interior Permanent Magnet Synchronous Motor(IPMSM) for Electric Vehicle(EV) is carried out according to the number of conductors. For this research, the analysis method of AC copper loss is introduced, and the loss characteristics are analyzed by classifying the components of AC copper loss according to the number of conductors. The analysis is carried out from the low speed to high speed region(5,000rpm, 7,500rpm, 10,000rpm). The analysis model is EV traction IPMSM of 8 poles 72 slots. To verify reliability of the analysis, 2D-Finite Elements Analysis(2D-FEA) software tool is employed.
