Abstract
An electrical machine includes a stator core and a plurality of windings subdivided into a plurality of multiphase motor cells, each multiphase motor cell having M windings associated therewith, and having a phase shift relative to other multiphase motor cells. The electrical machine may include N inverter cells coupled in series; wherein each inverter cell is a multiphase inverter; and wherein the voltage magnitude supplied to a corresponding multiphase motor cell is V/N. The electrical machine may include a sensor system in communication with the plurality of inverter cells and operative to commutate each inverter cell in a sequence.
