Electrical Signature Analysis (ESA) was developed originally at Oak Ridge National Laboratory to allow diagnostic related information to be gathered from electric motor driven devices via a remote non-intrusive current measurement on a motor power cable. The resulting signal with appropriate processing is sensitive to mechanical and electrical perturbations occurring in the motor and driven system. This technique has been applied to many different types of AC and DC motors with various driven machines. Recently the ESA technique has been extrapolated to evaluate electro-magnetic devices such as alternators and generators via analysis of their voltage output signals. The primary goal of this study is to investigate diagnostic methods from established non-intrusive ESA methods and apply them to sound reduction in automobile alternators, diagnostics for rotor and gearbox for helicopter and aircraft generators, and diagnosis of gear problems and electrical winding health for airliner auxiliary power unit generators.
