Abstract：The soft magnetic composite (SMC) material is made from metal particles insulated each other through mold pressing. The SMC material has unique properties such as isotropic magnetic properties and very low eddy current losses, however the hysteresis loss is greater and the magnetic permeability is lower than silicon steel sheet. So the difference with silicon steel sheet need to be researched deeply in regard to the application and magnetic performance. In this paper the magnetic characteristic of the SMC material is tested based on annular specimen method firstly, the demagnetization curve and the iron loss curve in different frequency are received. To compare and analyze the performance difference between silicon steel sheet and the SMC material in electric machines, two permanent magnet synchronous motors in which one is made of silicon steel sheet and the other is made of SMC material are designed. The magnetic field and the iron loss are computed and analyzed, especially the iron loss variation law in different frequency is derived through the simulation. The two prototypes are manufactured at last, the calculation validity is verified and the application range for the SMC material can be summarized through comparing the performance difference in the two prototypes according to the tested data.
