Abstract

The modal analysis technique and the finite-element method (FEM) were used to investigate the mechanical and electromagnetic vibration behavior of the stator of a synchronous machine. The presence of teeth characteristically decreases the natural frequencies of the stator. In addition, the distribution of the electromagnetic force densities was investigated. It was found that the finite-element software package FLUXMECA is a useful tool for computing sufficiently finely the distribution of the force density inside electrical machines and for analyzing the influence of the electric, magnetic, and mechanical structure on this distribution
