Fault Detection of Induction Motor Using Current and Vibration Monitoring

Induction motors are used worldwide as the “workhorse” in industrial applications. Although, these electromechanical devices are highly reliable, susceptible to many types of faults. Condition monitoring and fault diagnosis of induction motors are of great importance in production lines. It can significantly reduce the cost of maintenance and the risk of unexpected failures by allowing the early detection of potentially catastrophic faults. In this paper I have used both vibration and motor current signature analysis to detect the fault. The various fault discussed in this paper are- Mechanical fault such as bearing damage and Electrical Fault such as unbalanced voltage supply, single phasing. Condition monitoring, signal processing and data analysis are the key parts of the Induction Motor fault detection scheme.
