Paper Title:
Dynamic Performance of the Bearing-Rotor System in the Ultra-High Speed Electric Spindle with a Additional Supporting System Make up of the Permanent Magnetic Bearings
  Abstract

A novel method, aiming at solving the problem that the ultra-high-speed electric spindle tends to vibrate as its stiffness is small, using the repulsion of permanent magnets based on the theory that repulsion increased while the two magnets come close, is provided in this paper to design a electric spindle within additional support bearing system consist of two radial permanent magnet rings against each other. This paper also analyses the dynamic performance of radial permanent magnet bearings additional supporting system for ultra-high speed electric rotor system, result shows that the radial permanent magnetic bearings additional supporting system designed for improving the critical speed of the rotor system, reducing the rotor radial dynamic response, can effectively improve the dynamic performance and operational stability of ultra-high speed electric spindle rotor system.
