Flux Modulated Motor Using Magnetic-Geared Structure

This paper focuses on a flux modulated motor that consists of 3 parts: inner rotor, middle rotor, and stator. The inner rotor can be rotated when the middle rotor is fixed, and the middle rotor can be rotated when the inner rotor is fixed. In this way, this motor has 2 operation modes. The torque-speed characteristics of 2 operation modes is compared, and the difference is discussed.
