Abstract:In view of the complication of mathematical model in bearingless switched reluctance motors utilizing the traditional virtual work method which is based on the fixed angle system, this paper combines the rotating coordinate system with the virtual work method to establish the mathematical model of conical bearingless switched reluctance motors (CBSRMs), under two-phase operation mode. Considering radial and axial displacements of the rotor, the model can accurately describe the radial force, axial force and electromagnetic torque in the motor. Good characteristics of the mathematical model are verified by the finite element (FE) simulation. The model provides a reliable theoretical basis for the design of suspension control system. © 2018, Electrical Technology Press Co. Ltd. All right reserved.
