Abstract
A multiple-phase electric machine provided with multiple inverter power circuits is described herein. The present multiple-phase electric machine aim at performing configuration changes while reducing the loss of torque when machines are switched between configurations. This is done by forming groups of phases defining machine portions that are powered by a separate inverter power circuit and by switching the machine portions separately with controlled switching devices.
