Abstract :
This paper presents a suspension force modeling method for bearingless permanent magnet synchronous motors (BPMSMs) using Maxwell stress tensor method. By deducing the magnetic flux density of airgap in BPMSMs using magnetic circuit analytic approach, the suspension force model with rotor eccentricity is established. And then the suspension force of a surface-mounted BPMSM is computed by the finite element method. The simulation results illustrate the effectiveness of the proposed modeling method.
