ABSTRACT:
Methods and apparatus provide for commutating windings of a polyphase machine such that electromagnetic fields of stator and rotor phases of the polyphase machine produce at least one of motoring and generating torque, wherein the controller is operable to automatically vary at least one of a lead angle measured between the electromagnetic fields of the stator and rotor phases and rotor excitation parameters as a function of a rotational speed of the polyphase machine.
