Abstract Air-gap eccentricity is commonly occurred in large induction motors. Based on this fault, winding function approach (WFA) is carried out and theoretical derivation of WFA is also presented. In this way, the inductance matrix in the multi-loop model is calculated. A model of eccentric induction motor (1 200kW) is established based on such method and winding function translation coefficient is introduced to make more accurate calculation. In order to verify the feasibility, the result from modified winding function approach (MWFA) is discussed and compared with that from conventional winding function approach and that from finite element method.

Key words： Induction motor air-gap eccentricity multi-loop theory winding function approach calculation of eccentric inductances
