| Summary: | Aiming at the defect that the traditional bearingless switched reluctance motor cannot control the axial suspension force, so that the rotor cannot achieve five-degree-of-freedom suspension by itself, this study presents an innovative 12/14 conical bearingless switched reluctance motor. The structure and principle of suspension force generation is illustrated in detail. Meanwhile, mathematical model of the proposed motor is studied and established. Considering the radial and axial displacement of the rotor, the derived mathematical model could accurately describe the radial force, axial force and electromagnetic torque of the proposed motor. Finally, the effectiveness of the derived mathematical model is verified by finite element simulation.
