VIRTUAL INSTRUMENTS FOR ELECTRICAL MOTOR’S DIAGNOSTICS
L. Swêdrowski
Abstract:
The best results of electrical motor’s diagnoses are obtained using the methods based on spectral analysis of vibration signals or on analysis of supplying currents (in the case of electrical driving systems). The most numerous group of driving system breakdowns is connected with the damages of roll bearings. In this case very effective diagnosing can be obtained using envelope signal processing (ESP) technique. The research stand elaborated in the Faculty of Electrical and Control Engineering (TUG) enables to make research with ESP diagnostic method used for rolling elements bearings as well as supplying current analysis. The diagnostic system is based on virtual instruments using LabVIEW of National Instruments The stand is equipped in numerous motors with determined defects as well as the motors of the same type being in good condition, computer, specialized software built on the base of LabVIEW package. The results of measurement, as panels of virtual instruments, created in LabVIEW, are shown in the paper.
