Multi-Physics Multi-Objective Optimal Design of 5-DOF Magnetic Bearing System with High-speed Permanent Magnet Synchronous Motor

In view of the high-precision design requirements of suspension system under high-speed conditions, this paper used multi-objective genetic algorithm (MOGA) to carry out pareto optimization design of five-degree-of-freedom magnetic bearing system, and used finite element method to analyze the structure before and after optimization based on electromagnetic field, stress field and rotor dynamics theory respectively.
