Abstract
In this paper, the high speed motor hybrids with a radial-axial 3 degree of freedom hybrid magnetic bearing unit and BPMSM unit is proposed. The radial suspension force and magnetic field distributions with different magnetized mode are calculated. The losses are calculated and compared using time-stepping finite element method. The research results have shown that the high-speed BPMSM with Halbach array permanent magnet rotor has sinusoidal air-gap magnetic field, minimum losses.
