This paper describes the method for the analysis to obtain steady-state currents and torques of permanent magnet synchronous motors including space harmonics. A time-stepping finite element technique including the rotor movement is proposed, where both terminal voltage and load angle are given as the known values. In simulating the rotor movement, the suitable rotation step to take account of the effects of space harmonics, is determined. The agreement between calculated and measured results of the synchronous performance in an experimental motor is good.>
