Hybrid Drive of a Variable Flux Reluctance Motor and Switched Reluctance Motor

Abstract

A current superimposition variable flux reluctance motor for a traction motor of electric vehicles and hybrid electric vehicles are proposed. This motor can be driven using a 6-phase asymmetric inverter which is used to drive a switched reluctance motor. However, it is difficult to obtain a high efficiency in a low-speed and high-torque region. In order to solve this problem, a switching operation between the current superimposition variable flux reluctance motor and a switched reluctance motor is proposed in this paper.
