Simulation research of electric machine was done. In order to acquire all kinds of correct parameter values ,three-dimensional (3D) electromagnetic field analysis was made for magnetic flux density vector and no-load electromotive force of machine by means of powerful finite element analysis (FEA) software;and a couple simulation method of field and circuit was put forward for achieving whole simulation of machine and control system. Finally, according to theoretical research above, design characteristic and design method were put forward, meantime, a 12-poles prototype of ASCPM was manufactured. Correctness and feasibility of theory work are verified by means of the comparison of theoretical researchs and experiment results, and foundation is laid on further research on this kind of machine.
