Finite Element Analysis and Dynamics Charateristic Study for High-Speed Magnetic Suspension Motorized Spindle of CNC Machine Tools

Abstract:

According to magnetic suspension motorized spindle system, high speed motorized spindle system based on bearingless induction motor is presented in this paper. The prototype of high speed motorized spindle system with bearingless induction motor is studied and analyzed by using finite element analysis software Ansoft/Maxwell and Riccati transfer matrix method, and compared with high speed motorized spindle system supported by Active Magnetic Bearing (AMB). The results show that high speed motorized spindle system with bearingless induction motor has distinct advantage of simple and compact structure, which is easier to realize high speed and extra-high speed operation.
