A new operational mode for mixed-pole machines is presented. The proposed wound reluctance rotor machine can produce an n-phase rotor electric power from the rotor windings to a resistive or inductive load, independent of rotor torque, at any desired synchronous speed. The two-stator windings, with a different number of poles, are fed from two voltage source inverters on a common dc link. This type of machine can be used in applications that require control of both rotor torque and rotor electric power, such as contactless rotational antennas and turret systems. The machine mathematical model is presented, with open- and closed-loop control systems, simulated and experimentally validated.
