ABSTRACT
This chapter provides an overview of the software and hardware modules used in the development of an experimental test rig for the noninvasive diagnostic condition monitoring system. It deals with the development of an experimental rig for the diagnosis of faults related to induction motors. The chapter provides a detailed explanation of the various components used in the test rig design. It discusses the design of the LabVIEW program for the diagnosis of mechanical faults at various operating conditions of the induction motor. The LabVIEW software program created to reveal the characteristic fault frequencies is designed to accommodate the instantaneous power analysis (IPA) and park vector analysis algorithms, respectively. An adaptive threshold is derived for specific fault signature detections in the instantaneous power spectrum. The IPA technique was employed to identify the characteristic frequencies related to gear defects and bearings localized defects. Distributed faults create continuous types of vibration and cause premature failure of the motor bearings.
