Abstract
An electric machine with reconfigurable rotor poles. The machine may include a stator including a plurality of stator windings configured for generating a rotating magnetic field (RMF) and a rotor configured for rotating within the stator according to a torque induced by the RMF. The rotor may include a plurality of rotor windings wrapped around a plurality of circumferentially spaced rotor protrusions. The electric machine may include a rotor power transfer circuit operable for reconfiguring electrical excitation of the rotor windings according to a plurality of excitation modes.
