| Abstract: | This paper focus on diagnosing rotor winding faults in asynchronous motors by residual voltage after AC dump. First, through analyzing the reason of residual voltage, its properties were discussed. Then, the harmonics in the stator winding of residual voltages were compared between healthy and unhealthy motor. Finally, residual voltage can be used in rotor winding faults diagnosis was testified by simulating calculation and experiment. |
