Abstract
The hybrid magnetic bearings (HMB) stabilize suspension in equilibrium position by providing bias flux through permanent magnets. The loss generated during operation causes the temperature of the HMB to rise, which affects the stability of the magnetic bearing. In this paper, the loss and temperature of HMB are analyzed by finite element analysis software. The results show that the loss of HMB is mainly distributed in the rotor part, and the temperature of the rotor part is obviously higher than that of the stator part. The relationship between the structural parameters such as air gap length and pole width, and the loss of HMB is obtained by finite element analysis. According to the analysis results, the structural parameters are optimized by GAPSO. After optimization, the loss and temperature of HMB are significantly reduced.
