【摘要】 因集肤效应、邻近效应对扁铜线的影响,新能源汽车扁铜线电机的交流损耗计算越来越重要。扁铜线层数越来越多,单纯的2D模型仿真计算已经不能满足其精度要求,研究了一种利用外电路联合仿真的方法。仿真计算和样机实测对比结果表明,该方法能够满足工程应用要求。更多还原

【Abstract】 Because of the influence of the skin effect and theproximity effect on the hair-pin winding,the calculation accuracy of the AC loss of the hair-pin winding motor of new energy vehicles becomes more and more important. With more and more layers of the hair-pin winding, the simple 2 D model can not meet the calculation accuracy requirements. A method of joint simulation using external circuit was studied. The comparison between simulation and prototype showed that the method can meet the requirements of engineering application.更多还原
