A calculation procedure to investigate harmonic losses of interior permanent magnet motors driven by PWM inverters is proposed. The 3-D nonlinear time-stepping finite element method is carried out with the voltage waveform, which is generated by the PWM inverter due to the controller command of the armature current. The calculated electromagnetic potentials at each finite element are decomposed into time-harmonic components to understand the harmonic characteristics separately. The calculated… CONTINUE READING
