Performance evaluation of mixed pole machines with electromechanical torque and rotor electric power

This paper presents the performance and steady state analysis of mixed pole machine with a new mode of operation where n-phase electric power can be transferred to a load mounted on the rotor, such as rotational antennas and turret systems. The machine construction and theory of operation for this new mode is illustrated. System performance at steady state operation is investigated using both simulation and experimentation. The performance assessment includes machine torque, electric efficiency, mechanical efficiency, and total efficiency. Also, the effects of electrical loading and stator voltage on the rotor torque and rotor electric power are considered.
