A brief review of condition monitoring techniques for the induction motor

The induction motor is widely used in industry owing to its simple construction and low cost. In this paper, we present a state-of-the-art review of condition monitoring techniques for the induction motor. As the induction motor is used in many production processes, its uninterrupted and cost-effective functioning is of prime importance. Condition monitoring of the induction motor enables detection and prediction of different developing faults. Various techniques have been reported in literature for induction motor fault detection. In this paper, a brief review of these techniques is presented. Major induction motor faults and their sources are also described.
