Description
Summary:The history of faults of induction motors is nearly the same age as the history of induction motors. In the past, induction motors were used in limited places and the faults were solved by taking various measures such as grounding, using over-current protectors, or using voltage-regulators. Nowadays the induction motors are used in a wide area of applications. Therefore the diagnosis and repair of faults are important to prevent costly damage and downtime in commercial and industrial facilities. The main faults of induction motors are broken rotor bars, winding faults, and mechanical faults. The rotor faults can be observed as harmonics in stator current. In this paper broken rotor bars are modeled by using MATLAB/Simulink tool. The results demonstrate that MATLAB/Simulink model can be used for educational purposes.
