Abstract

In this paper, a built-in hybrid magnetic bearing (BHMB) with a permanent magnet (PM) motor is proposed to reduce the axial length of the system. The BHMB shares the same distributed hollow rotor with an external PM motor. The structure and principle of BHMB are illustrated. The mathematic model of BHMB is deduced to design parameters, and the influences of parameters are analyzed. To improve the performance indexes of BHMB, a multi-objective optimization method based on Taguchi method is proposed. The values of parameters of BHMB can be chosen according to the proportion of each parameter. Finally, the finite element analysis (FEA) and experiment are used to verify the correctness of BHMB.
