Abstract

A suitable model for vibrations incorporating the effects of damping is described in this paper. Information on the vibration behaviour of the stator of electrical machines is obtained using an experimental modal-analysis. This paper presents a new measurement technique for the determination of the resonances, and the vibration behaviour at resonance, of stators and rotors of electrical machines. The measuring techniques, instrumentation and experimental arrangements are described. Experimental results on the vibration behaviour of a 120 hp induction motor stator are provided with a view to determine the actual role played by a stator in the production of noise and vibrations.
