Abstract
This paper presents a method to analyze radial force densities acting on each stator tooth of an induction motor with skewed slots. Two-dime nsional finite element method is used for electromagnetic field analys is of an induction motor, and skew effects are considered by coupling several disks cut by planes perpendicular to the shaft. Radial force d ensities as a source of vibration are calculated along the surface ele ments of each stator tooth and its time harmonics are examined by disc rete Fourier decomposition.
