Modelling method for time‐varying suspension system of axial split‐phase bearingless switched reluctance motor
Abstract The rotor of the axial split‐phase bearingless switched reluctance motor (ASPBSRM) is structured with convex poles. The magnetic flux between the stator and the rotor varies with the rotor position, resulting in time‐dependent displacement stiffness and current stiffness coefficients of the...

| description | Abstract The rotor of the axial split‐phase bearingless switched reluctance motor (ASPBSRM) is structured with convex poles. The magnetic flux between the stator and the rotor varies with the rotor position, resulting in time‐dependent displacement stiffness and current stiffness coefficients of the suspension force. This scenario leads to a time‐varying characteristic of the suspension system. This study analyzed the electromagnetic characteristics of the suspension force in the ASPBSRM to characterize the time‐varying suspension system accurately. The study elucidated the hinge relationship between the magnetic flux in the suspension system and the rotor position. Moreover, a mathematical model for the suspension force considering the magnetic flux multitooth hinge was constructed by leveraging the advantages of the Maxwell stress method for the localized modelling and adopting the concept of the main edge magnetic path parallel analysis. Finally, the effectiveness of the model was verified through finite element analysis. |
