Short summary
This paper presents an electromechanical hybrid model combining a driving circuit and a TWUSM. (1) A driving circuit model combining circuit components with the load-dependent equivalent circuit model is proposed to simulate the real electric network. (2) The teeth discretized method is employed to refine the contact status and interaction forces limited to the teeth space, which improves the accuracy of the rotor step response not only in the rising time, but also the steady value.
