Modelling of healthy and faulty three phase induction motor in LabVIEW

Induction machines are undoubtedly a crucial part of the industry and so they need to function in a stable and secured manner. Negligence in maintenance or careless operation of the induction machines can induce faults in the machines resulting in failures and ultimately giving rise to loss of funds and resources. In this paper, three phase induction motor model has been designed in LabVIEW. It has been modeled in such a way that it can be simulated as an ideal or healthy motor as well as a faulty motor having faults such a stator winding fault, rotor fault and bearing or eccentricity fault. It can be simulated for various ratings of induction motors and the values of current, voltages and different waveforms associated with the faults can be obtained which can be used in any application where faults in induction motors need to be detected.
