A switched reluctance (SR) motor has an extremely simple and robust structure, and high heat capability because of no magnet. Therefore, these advantages are suitable for an application of the in-wheel SR motor to electric vehicles. This paper presents an in-wheel SR motor improved torque density. The proposed SR motor has two features for improvement of torque density; the first one is asymmetrical rotor pole structure that torque is improved in only one rotational direction; the second one is the overlap of the excitation to increase effective voltage. In the proposed SR motor, the maximum torque volume ratio is about 38 N・m/L.
