CALCULATION OF INDUCTANCES OF INDUCTION MACHINES UNDER AXIAL NON-UNIFORMITY CONDITIONS

Hamid Reza Akbari - Siavash Sadeghi - Arash Hassanpour Isfahani

   A modified model for calculating the inductances of induction machines, considering axial non-uniformity is proposed. By means of the proposed model, inductances of a three-phase squirrel-cage induction machine under eccentricity and misalignment conditions are calculated. The effects of stator and rotor slots, rotor skewing and several rotor asymmetries on inductances in these conditions are investigated.

Keywords: induction motors, inductances, axial non-uniformity, eccentricity
