This paper describes the damping effect by cage bars of self-starting permanent magnet synchronous motors when load changes suddenly. A time-stepping finite element method including the rotor movement is used, where both terminal voltage and load torque are given as the known values. Transient current, torque and angular speed are computed respectively. In simulating the rotor movement, the suitable time step to take account of the effects of space harmonics, is determined. The agreement between calculated and measured results of the transient performance in an experimental motor is good.
