A new technical article has been published about motor testing in NETA World Magazine, titled “Condition Assessment Of The Induction Motor Based On Vibration And Current Signature Analyses”.
The early diagnosis of fault conditions in electrical machines is important for increasing the reliability of the machine drive systems. One noninvasive method for condition-based monitoring of electrical machines is vibration measurement. Motor vibration analysis can detect electrical or mechanical malfunctions on stator, rotor, and bearings as well as external sources of vibration. This article includes an overview of the detection techniques employed and discusses the vibration and current signature analysis of a squirrel cage induction motor.
