Modal Analysis of Stator and Rotor in Large Capacity Permanent Magnet Motor

Abstract:

This paper presents the modal analysis of stator and rotor in large capacity permanent magnet motor with exterior rotor. Modal analysis of motor has vital significant to suppress vibration and noise of the motor in operating. Models of stator and rotor in motor with exterior rotor are analyzed by finite element method. Calculation results of different models indicate that the laminations and windings in large capacity permanent magnet motor have substantial effect on natural frequencies and vibration shapes of stator of the motor. Magnets on interior surface in the exterior rotor have some influence on the modal of the rotor.
