文章预览

This paper focuses on the stiffness and damping characteristic of hybrid magnetic bearing for high-speed electrical machine. Firstly, it analyzes the structure and working principle of hybrid magnetic bearing, according to the bearing’s magnetic circuit properties, it deduces the equation of the bearing’s magnetic force with displacement and current. Then, combining with the controller parameters it deduces the stiffness and damping equation of magnetic bearing. At last it simulates the stiffness and damping characteristic curve, and the obtained simulation results can give theoretical support for rotor dynamic analysis and modal analysis.
