Overview of Sensorless Diagnostic Possibilities of Induction Motors with Broken Rotor Bars

During the past few decades there has been a continu-ally increasing interest and investigation into fault detection and diagnostics of induction motors. There are various different diagnostic approaches and methods to detect faults in induction motors. Attention should be paid to the fact that as induction motors are often used in critical duty drives, it is essential not to disturb the working cycle of the motor in any way while performing the...
