This paper describes a method for the dynamic simulation of a cage induction machine with static and dynamic air gap eccentricity. The method is based on the winding function theory and extension of this theory to the nonuniform air gap case. A method of calculating all inductances in a machine with both static and dynamic air gap eccentricity is presented and a numerical analysis of a machine with specified parameters is presented. Stator line current spectra collected experimentally for both the static and dynamic eccentricity conditions confirm the results obtained by the proposed numerical model.
