Analysis and Comparison of Novel Yokeless Double Rotor Mutually Coupled Switched Reluctance Motor

This paper proposed a new seven-phase, yokeless, two-rotor switched reluctance motor with flux between adjacent stator teeth. The motor adopts a two-rotor structure and increases the conducting area of each phase winding by using the self and mutual inductance between the windings, thus increasing the torque density and power density of the motor while reducing the motor torque pulsation. In this paper, the topology and operating principle of the proposed motor are firstly introduced. The motor model is established using the equivalent magnetic network method to further analyze the thrust characteristics of the motor, and the results are verified by the finite element method.Finally, the new motor proposed in this paper is compared with the conventional switched reluctance motor based on the analysis results.
