Suspension force model optimization method of centralized magnetic suspension asynchronous motor

The invention discloses a suspension force model optimization method of a centralized winding magnetic suspension asynchronous motor, which is suitable for a single-phase suspension asynchronous motor and a three-phase suspension asynchronous motor adopting centralized windings. According to the method, firstly, the number of all harmonic pole pairs capable of generating suspension force between a torque winding and a suspension force winding is found, then suspension force equations of a traditional single-phase magnetic suspension asynchronous motor and a traditional three-phase magnetic suspension asynchronous motor are corrected, and accurate values of correction factors are calculated. And finally, a suspension force/current conversion module is improved in a control system of a traditional single-phase magnetic suspension asynchronous motor and a control system of a traditional three-phase magnetic suspension asynchronous motor. According to the invention, the suspension force model of the traditional m
