Abstract

Broken bar faults are common in induction cage motors and can cause a variety of problems. This is the reason why there is continuous research on techniques for prompt detection. In this work a study of the influences of the broken bar fault to the electromagnetic characteristics of the induction motor is presented, using an asynchronous cage motor and FEM analysis. To this direction two models have been created and studied: a healthy one and a model with a broken bar fault. Additionally, a new approach on the detection of the broken rotor bar fault through the electromagnetic torque monitoring is suggested.
