This paper presents an analytical approach to modelling radial magnetic force acting on stator surface of induction motors, this model covering the most important causes of magnetic noise such as saturation, eccentricity, slots and winding distribution. The study of magnetic noise due to eccentricity is given, which demonstrate the adverse effect of this phenomena, often occurring due to production.
