To achieve the decoupling control of the electromagnet torque and suspension force in
bearingless switched reluctance motor (BSRM), a novel single-winding BSRM with hybrid
rotor is proposed (HRBSRM). The HRBSRM is composed of a 12-tooth stator and a hybrid
rotor consisting of an 8-tooth salient part and a cylindrical part. Based on virtual
displacement method, its mathematical model of suspending force is deduced. According to
the motors' characteristics of full-period suspension, a control method under two-phase …

Purpose–This paper seeks to propose a novel bearingless switched reluctance motor
(BSRM). Design/methodology/approach–The operating principle and structure
characteristics of the proposed three‐phase 12/8‐pole BSRM is analyzed in detail. Finite
element method‐based calculations are applied to a prototype and some important
characteristics are obtained, including radial force, static torque, air‐gap magnetic flux
density, and effect of control winding current on the torque, where magnetic saturation is …
