Rotor broken bar fault accounts for more than 5% in induction motor faults. The frequencies (1 ± 2s)f1 in motor current are recognized as the fault characteristics to detect the fault. However, when the traction motor works under light load, e.g., idling condition, the fault diagnosis algorithm will be invalid as the characteristic frequency approaches to the fundamental frequency f1. In this paper, a low frequency injection algorithm is adopted to detect the rotor broken bar fault for an induction traction motor under the low load condition. Firstly, the fault characteristic frequency generated by the injected voltage is analyzed. Then the selection of the injected voltage frequency is discussed, and the implementation of the low-frequency voltage injection algorithm for the motor is developed. Finally, the proposed method is validated through the experiment results.
