Abstract

There are many failures of AC motors in the industry for different reasons and huge losses are affected. This failure takes some time to happen and the cause slowly affects the motors. In this project report, the neural network comes with a solution to the problem. The neural networks able to diagnosis the incipient AC motors faults. The network collects all the possible causes to any failure and analyzes it with existing trained datato determine the statusof the motor. For example if the motorhaving degradation on the winding insulation resistance, the network will collect the status of the insulation resistance and compare it with the allowable value of the insulation resistance, thus the output states the future failure with the current value ofthe insulation resistance on the motor's winding. This project report covers onthree fault outputs which are bearing fault, winding fault and overheating fault. All these outputs depend on certain inputs where the inputs are the cause towards the failure. The artificial neural network has various types of usage. For the prediction purposes, feedfoward-back propagation network topology will be used. This topology will be is with appropriate training function. The training function for example, Resilient-Backpropagation will be trained and provides values for weights and biases of the network topology. The biases and weights are used to analyze any input fed to this network and come out with its prediction. Furthermore the project report also deals with MATLAB simulation and toolbox. TheMATLAB software is able to tolerate the neural networks where all the command and application are in MATLAB based.
