Computer-based diagnostic system of the induction motor

This paper presents a realization of low cost, portable measurement system for induction motor fault diagnosis. The system consist of four-channel data acquisition recorder and laptop computer with specialized software. The diagnostic software takes advantage of motor current signature analysis method (MCSA) for detection of rotor and stator faults, voltage unbalance and mechanical load misalignment. For diagnosis purposes the neural networks techniques are applied. (Computer-based diagnostic system of the induction motor).
