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 2D 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.
