Conventional models of squirrel cage induction machines do not consider interbar currents. For the accurate numerical investigation of electrical rotor asymmetries interbar currents have to be modeled. A mathematical model of such a machine with interbar conductances is presented in this paper. An approach for the parametrization of the interbar conductances is introduced and discussed.
