Principle of a Novel Dual-mode Reluctance Motor for Electric Vehicle Applications

This paper proposes a novel Dual-mode Reluctance Motor which can switch the motor mode between a switched reluctance motor and a synchronous reluctance motor to enhance the high efficiency region. It is found that the efficiency of a synchronous reluctance motor mode is high with respect to that of a switched reluctance motor mode in higher rotational speed and low power region because of the lower iron loss specification of the synchronous reluctance motor. This enhancement of the high efficiency region is suitable for electric vehicle application.
