Analiza drgań stojana silnika BLDC pochodzenia magnetycznego

Vibrations and acoustic noise are some of the fundamental problems in the design and exploitation of rotating electrical machines. The aim of this paper is to use finite element multi-physical model – electromagnetic and mechanic – in order to predict the forced vibrations due to Maxwell forces in stator structure of BLDC. In aim of verification numeric calculations experimental measurements was made by sensors measuring radial component of acceleration in selected point. A vibration prediction model for the BLDC motor is constructed in this paper, the model is verified be experiments, with acceptable accuracy.
