Current and Torque Harmonic Analysis of Six-Phase Induction Machine With Pwm Inverter Supply Under Fault Conditions
Six-phase induction machines have attracted attention due to their high efficiency and enhanced fault tolerance. Compared to conventional three-phase machines, six-phase drives can operate under the open-circuit of one, two, or even three stator phases, while still generating electromagnetic torque and sustaining mechanical load, although torque ripple, harmonic distortion, and some efficiency loss increase.
