Magnetic field analysis in asynchronous motors with six–phase windings

Abstract

In this paper is presents the results of the magnetic field analysis produced by the two layers stator six–phase windings, of the asynchronous motor for electric traction compared to the three–phase stator winding of mass–produced asynchronous motors. Applying the finite element method, was concretized the shape of the magnetic induction curve in the air gap and the values of magnetic flux and induction for different stator winding schemes were presented. The obtained results give the possibility to select the stator winding scheme, which has technological advantages for the asynchronous motors used in electric traction.
