However, the magnetic field generated by the levitation winding and the main winding of this generator interacts and couples each other on the magnetic circuit, and there is a complex nonlinear strong coupling relationship between the levitation force and the generated voltage. The mathematical model derivation of the system, the nonlinear solution Coupling and operation control are very difficult, and the performance of suspension and power generation needs to be improved

[0004] The document "Principle and Realization of Three-phase Series Excitation Bearingless Switched Reluctance Generator" published in "Journal of Electrotechnical Society" in 2013 announced a three-phase series excitation magnetic levitation switched reluctance generator, which can further reduce the The cost of the power controller, but this kind of motor also has the problem of strong coupling between the suspension and the power generation system

However, in this type of wide-narrow pole mixed stator magnetic levitation switched reluctance generator, there is still a certain coupling between the generator electrode and the levitation pole, and the coupling between the levitation poles with two degrees of freedom in the radial direction is also relatively large. The control of the power generation function has a greater influence on
