Abstract :
In allusion to the characteristic of high speed motorized spindle, an innovation motorized spindle system based on 5-degree-of-freedom bearingless induction motor was put forward in the paper. The innovation suspension motor system consists of two independent suspension units: the 2-degree-of-freedom bearingless motor and the AC-DC-3-degree-of-freedom hybrid magnetic bearing. The prototype is designed and simulated to analyze the magnetic circuits by using finite element analysis software Asoft/Maxwell. The results indicate the validity of the design of high speed motorized spindle with bearingless induction motor, and some parameters have been optimized according to the simulation results.
