摘要：
A method for calculating the loss of permanent magnet synchronous motor (PMSM) under inverter supplied is proposed. It includes calculation of voltage waveform and transient current waveform under multi-mode PWM modulation, and the current waveform is taken as excitation to he input to the finite element simulation model, Then stator core loss, rotor core loss, permanent magnet eddy current loss and stator winding loss considering skin effect are calculated in finite element simulation. The calculated values of the prototype agree well with the measured data and verify the feasibility of the calculation method.
