Lately the permanent-magnet-excited synchronous motor is replacing the DC control motor. However, it seems that investigation and analysis of PMSM have not been made adequately and sufficiently. In this paper SV method will be applied to analysis of PMSM, to obtain a new steady state vector diagram, which will reveal new aspects of performances of PMSM. They will provide superior characteristics to control of PMSM.
