摘要
对混合动力电动汽车用永磁无刷直流电机进行电磁场分析和参数计算。利用有限元方法对电机的磁感应强度、磁通以及磁力线分布等进行求解,并提出了漏磁系数、极弧系数和电感的计算方法,与实验结果比较证实了计算方法的正确性。
This paper describes the electromagnetic field analysis and parameter calculation of a permanent-magnet brushless DC electric machine for hybrid electric vehicles application. The magnetic induction density, flux and magnetic field distribution of the electric machine are solved by finite element method, and the calculation methods of the leakage culation coefficient, pole-arc cofficient and inductance are presented respectively. The ealresults verify that this method is accurate compared with the test one.
