Abstract:
Rotor displacement control of a bearingless switched reluctance motor （BLSRM） with single-winding stator is proposed. First， the structure and working principle of BLSRM are briefly introduced. The equivalent magnetic circuit method is used to establish a mathematical model of suspension force and stiffness. In addition， a rotor-dynamic model is established to attain the relation between force and rotor displacement. Finally， a prototype motor is designed and the suspension control of the motor is implemented. The validity of the proposed method is verified by experimental results.
