Rotor Displacement Control of Bearingless Switched Reluctance Motor with Single-Winding Stator
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.
