Numerical modelling and experimental analysis of vibratory and acoustics behaviours of a special design squirrel-cage three-phase asynchronous machine

The paper presents a comparison between the obtained results from testing a special design 5 kW squirrel-cage three-phase asynchronous machine and the numerical model of the same machine, simulated under the FLUX2D Finite Element Software. The aim is to validate the numerical model in the loaded and unloaded cases. The resulting model will be used for further research into the vibratory behaviour and noise of the motor. In this paper, an experimental approach is used to show the influence of load on motor vibration and noise levels. The relation between the natural frequencies of the stator, the frequencies of the forces causing vibration and the noise of the motor, is studied by analysing several sets of measurements.
