This paper deals with the expression of the high-frequency model of permanent magnet synchronous motor (PMSM) driven by a PWM inverter. The leakage current (common-mode current) flows through stray capacitance among stator windings and iron core (frame) of a synchronous motor at the switching instants of inverter transistors. A mathematical model of high-frequency model of PMSM are derived voltage and current data at the time of a PWM inverter drive based on system identification. It is verified that the proposed model can simulate oscillating current of various operating points on some motors.
