Two forms of permeance function are presented and compared. The mixed-eccentricity fault is studied because it generalizes better the case encountered in any machine. IM inductances are calculated by using the modified winding function and including space harmonics of winding functions. It is also analytically detailed the genesis of the eccentricity signatures allowing the diagnosis. Coherence of simulated and experimental results in term of frequency content proves a validity of the study.
