Abstract

In this paper, the unbalanced magnetic pull and eccentric mass force which caused vibration of the rotor are introduced. The virtual displacement method is employed to solve the two kinds of force. The inherent characteristics of rotor are analyzed through finite element method and experiment. The dynamic response and axis locus of rotor under the action of unbalanced magnetic pull and eccentric mass force are studied in detail. The relationship between the vibration and rotating speed of rotor is concluded. The theoretical basis for the rotor safe and reliable operation of the high speed permanent magnet synchronous machine is provided.
