This paper proposes the use of the park transformation mass center applied to the stator currents as a method for diagnosing the occurrence of stator winding faults in induction motor. Induction motor stator currents are first measured and recorded. Then, the park transform is applied to the obtained currents in order to obtain a specific pattern that allows the identification of the stator winding fault. For a healthy motor, a single point in a dq-plane is obtained. However, for an induction motor with some stator winding fault one obtains a circle, in the dq-plane, which is dependent on the fault severity. Accordingly to this relationship a fault severity is reported. In order to show the applicability of the proposed technique, several simulation and experimental results are presented.
