| Abstract: | This paper proposes a novel variable flux reluctance motor without dc‐field coils. The stator of this motor has only armature coils. The proposed motor can control the torque‐speed characteristics by increasing or decreasing the field voltage that is superimposed on the armature currents. In this paper, the operational principle of the motor is described, and the N–T characteristics are computed by finite element analysis under vector control. In addition, the N–T characteristics are compared with a conventional variable flux reluctance machine with armature and dc‐field coils. |
