Abstract :
Original results of numerical simulations of an induction machine with local magneto-mechanically coupled FE model are presented. The coupling is implemented locally as a stress dependency of the magnetization properties of lamination. The mechanical load is due to the magnetic forces and shrink fitting of the core into the frame. Large local stresses are caused. They reduce the magnetization of lamination and increase the stator current. The resistive power losses increase and add to increased iron losses due to stresses. The efficiency of the machine is reduced
