Abstract
This paper investigates the diagnosis of not only broken-bar but also broken-end ring faults. The difference between the broken bar and broken end ring is clarified experimentally by the Fourier analysis and the wavelet analysis of stator current. Moreover, the electromagnetic field in the healthy rotor and the rotor with broken bar is analyzed to clarify the effect of the failures.
