Abstract

This paper deals with the procedure of calculating the vibration of a claw-pole generator. The stimulating forces of magnetic origin are calculated for several speeds. For the calculation of the displacements, the total generator system (stator plates with windings and housing) is taken into account. The displacement magnitude of the housing surface mainly causes the audible noise. The procedure makes it possible to ascertain the vibratory condition of an electrical machine just by means of the design and material data. Some results of stator vibration are presented and compared with measurements
