Abstract
This paper presents the experimental study of three-phase squirrel cage induction motor broken rotor bars diagnostics. Tests have been performed with two different machines, one through a frequency converter and the other supplied directly from grid. This comparison has been presented, as the use of frequency converters changes the traditional current spectrum of the machine and hence the diagnostic of such machines becomes more difficult. Necessity for further study on the behavior of the frequency converter in the weak grid is pointed out.
