Abstract

This study investigates the effects of the spatial harmonics of magneto-motive force that appear in the air-gap of aluminum-cage induction motors, proposing some techniques for their mitigation. With respect to previous researches, special magnetic wedges to be mounted in the stator opening regions of semi-closed slots of existing motors are proposed, together with a special winding layout having a very low magnetomotive force harmonic content. Both 2D- and 3D-FEM numerical simulations have been carried out to quantify the problems and to understand the potential benefits of inserting the stator wedges. At the end, the mechanical feasibility of the proposed wedges is considered together with some attempts at implementation.
