A 2D-model of the induction motor: an extension of the modified winding function approach

In this paper, a method to calculate the inductances of an induction machine with axial nonuniformity is presented. The analyzed axial nonuniformities are skew and rotor eccentricities. The inductance calculation is based on an extension of the modified winding function approach. Theoretical fundaments of this extension are presented. The coupled magnetic circuits approach has been used for modeling the induction machine. Experimental results that validate the proposal are also presented.
