Abstract The producing principle of radial suspension force for bearingless permanent magnet synchronous motors (BPMSMs) is elaborated. And then, according to the magnetic circuit principle of BPMSMs, the analytical model of the inductance matrix is obtained. Based on the inductance model and virtual displacement principle, a relatively accurate mathematical model of BPMSMs is derived. This analytical model takes the rotor eccentricity and the coupling relationship of the windings into account, and could describe the radial suspension force and electromagnetic torque more accurately. In order to confirm the validity and feasibility of this model, experimental studies are carried out on a surface-mounted BPMSM. Experimental results indicate that the static precision and dynamic response of the BPMSM can be effectively enhanced by using the proposed model.
