MODELING a transistor converter-fed permanent magnet poly-phase machine and a variable-frequency drive controller under non-sinusoidal back-EMF conditions


The paper presents a model of a poly-phase permanent magnet motor of the marine propulsion drive energized by multistage VSI. The model defines more precisely the non-sinusoidal waveform of back-EMF and its impact on the current distortion and electromagnetic torque ripples. The paper concludes by analyzing simulation results that have shown significant… (More)
