Current harmonics analysis as a method of electrical faults diagnostic in switched reluctance motors

Abstract

Diagnostic method of electrical faults in switched reluctance motors (SRM) based on current harmonics analysis is presented in this paper. The classification of electrical faults in SRM's has been discussed, simulation model and laboratory setup presented. For the SRM motor of 6/4 design the conclusions drawn from the tests conducted both in the simulated and laboratory conditions for regular operation and selected electrical faults. The electrical fault type found in the machine was determined on the content of harmonics of higher order in the source current. The conclusions are included.
