Abstract

The calculation of induction machines with squirrel cages using the finite-element method (FEM) requires a transient solving process. The rotation has to be taken into account. Therefore, a rotating air gap is implemented. The formulation for the transient solver is given. Finite-element models of an induction machine with centrical and excentrical positioned rotor are calculated. The formulation for the computation of the surface force density on the stator teeth is presented. For both variants of the induction machine, the forces are calculated and compared.
