Performance evaluation for mixed pole machines with electromechanical torque and rotor electric power and stability analysis

This paper presents the performance, steady state and stability 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. This type of machine can be used in applications that require control of both rotor torque and rotor electric power, such as rotational antennas and turret systems. The performance includes machine torque, electric efficiency, mechanical efficiency, total efficiency and system stability. Experimentation using a prototype machine confirms the simulation results.
