Multiple phase electric machine, drive and control

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. 本文描述了配备多个逆变器电源电路的多相电机。该多相电机目的是执行配置改变，同时减少机器在配置之间切换时的力矩损失。这通过形成限定由单独的逆变器电源电路供电的机器部分的相的组并且通过分别用受控的开关器件切换机器部分来进行。
