Abstract: Electrical Signature Analysis (ESA) is a powerful prognostic and performance tool for analyzing electric machinery through the measurement of the effects on the magnetic field as observed in voltage and current. This white paper explores how various induction motor and load conditions affect the magnetic field and spectral characteristics of measured values. We will delve into the mathematical models for radial and torsional conditions, the impact of driven loads, and the influence of power quality on the motor’s performance.
