In this paper, Radial Electromagnetic Force Wave, which causes the magnetic noise of the permanent magnet synchronous motor used in the electric vehicles of the Shanghai Expo, is studied by programming with ANSYS Parametric Design Language (APDL). The magnetic properties such as magnetic induction, magnetic field, magnetic flux density between the stator and the rotor are researched at no load and three-phase voltage load. Then all of the data is combined with Maxwell’s equations to calculate the space distribution and time distribution of radial electromagnetic force wave. Finally, it is made a main conclusion that main frequencies of radial electromagnetic force wave at the 3-phase voltage load are 200*k Hz (k=1, 2, 3…) and the corresponding levels are 3*k (k=1, 2, 3…).What’s more, it is also concluded that the radial electromagnetic force wave gain at Level 9 and 600 Hz reaches the peak.
