DIAGNOSTIC SYSTEM FOR INDUCTION MOTOR STATOR WINDING FAULTS BASED ON AXIAL FLUX
Journal Title: Power Electronics and Drives - Year 2017, Vol 2, Issue 2
Abstract
The article presents the results of research on the use of an axial flux in the diagnostics of induction motor stator winding fed by a frequency converter. Voltage signal waveforms proportional to the axial flux were registered during motor operation in various conditions and were analysed with regard to the detection of stator winding short circuits. The taps of the selected coil turns of stator phases were introduced into the tested motor, which allowed to physically model inter-turn short circuits. The structure and the operation of the computer system used to monitor the state of induction motor windings were discussed. The developed diagnostic system was made in the Na-tional Instruments LabVIEW environment. The first part of the article is devoted to the issue of the analysis of the axial flux in the detection of induction motor stator winding faults. The second part presents the results of experimental research conducted using the developed diagnostic system.
