Abstract

In this paper, a two dimensional transient study of induction motor starting is presented. The analysis is based on the coupling between mechanical motion, electric circuits and magnetic field equations of the machine. The electromagnetic field discretization is obtained by a FEM-BEM hybrid method in order to account for movement and saturation effects. The mechanical motion is solved using a time-stepping procedure in which the electromagnetic torque computation is based on the numerical solution of the magnetic field of the machine. In order to study the transient performance of the machine, we have chosen some typical variations of the load torque. For these cases, we show the transients of the three phases armature cur
