BOSSIO, G. et al. A model for induction motors with non-uniform air-gap. Lat. Am. appl. res. [online]. 2005, vol.35, n.2, pp.77-82. ISSN 0327-0793.

Equations to calculate inductances of induction motors, considering non-uniform air-gap, are proposed. The analyzed air-gap variations are static and dynamic eccentricity and stator slots. The equations for inductance calculation, obtained from the modified winding functions and the energy stored in the air-gap, allow considering the effect of rotor bar skewing. Experimental results that validate the proposed method are presented.

Keywords : Air-Gap Eccentricity; Induction Motors; Modeling; Winding Function Approach.
