The aim of this paper is to present and compare two modeling methods of the inter-turn short circuit fault in the stator winding of a cage induction machine. The first method is a Coupled Magnetic Circuit Method (CMCM) and the second method is a Permeance Network Method (PNM) which allows taking into account the saturation effect on the fault signature. The simulation results show that by proper modeling...
The incident of fault conditions, especially bearing defects, in modern drives has increased. Bearing defect and the resulting asymmetry of the airgap is considered most difficult to detect especially under inverter operation. In order to develop and test monitoring methods it is necessary to carry out extensive measurements at various kinds and levels of eccentricity. As the air gap length of modern...
