Short-circuit faults in windings due to the deterioration of insulation is one of the most common faults in motor drive systems. An easy and effective fault diagnosis method is urgently required to ensure a highly reliable operation. The magnetic field in the stator of motor is found to change after the occurrence of the short-circuit fault and it is clear that a change of magnetic field is affected by the frequency of voltage applied to the winding. In this paper, based on this phenomenon, a new identifying system which diagnose a stator slot in which a short-circuit fault has occurred is developed. In this paper, firstly, a new means of identifying a stator slot with a short-circuit fault is explained. Secondly, in order to realize the method as an identifying system, the prototype system is developed. Finally, by using this identifying system, magnetic flux density of each slot directly above are measured, the effectiveness of the system is evaluated.
