Abstract
In permanent-magnet synchronous machines (PMSMs) electromagnetic forces are identified as the principal source of vibrations and noises. In this article, first of all the sources of magnetic forces in PMSMs are analyzed. Then, an analytical method for the calculation of radial forces on the base of the stator tooth created by electromagnetic sources in PMSMs is presented. Finally finite element method (FEM) is used to corroborate analytical results.
