Abstract

The condition monitoring of the induction motor can significantly reduced the maintenance costs by early detection of the motor’s faults, which could be expensive to repair. In this paper we found some results on non-invasive detection of broken rotor bars in squirrel-cage induction motors. The applied method is so-called “motor current analysis by virtual instrument” (MCAVI) which utilizes the results of spectral analysis of the stator current. The diagnosis procedure was performed by using virtual instruments (VIs). Furthermore, this method which might help to develop diagnostics of broken bars and performance evaluation of induction motor in the near future’s application..
