Abstract

A drive and motor system and method for a six phase machine with negligible common-mode voltage is provided. The six-phase machine includes six phase windings divided into at least two windings groups configured to generate a zero common-mode pulse width modulation. The drive and motor system and method can also include at least one direct current source and a six phase inverter switching between positive and negative power of the at least one direct current source.
