Influence of rotor structure on the torque characteristic of a novel Claw Pole Type Half-Wave Rectified Variable Field Flux Motor

Recently development of the new concept motor for EV or HEV becomes very active. The wider torque and speed controllable operating range and high efficiency under driving area are needed for traction motor. As a novel motor candidates, we proposed a novel Claw Pole Type Half-Wave Rectified Variable Field Flux Motor (CP-HVFM). This motor is simple and robust brushless structure and has variable field flux performance. This paper describes the influence of the rotor structure on the torque characteristic of CP-HVFM.
