LabVIEW based Condition Monitoring of Induction Machines
This paper focuses on experimental results to prove that motor current signature analysis (MCSA) can diagnose shorted turns in low voltage stator windings of 3-phase induction motors using LabVIEW. The diagnostic strategy is presented and variables that influence the diagnosis are discussed. Current spectra from motors with short-circuited turns (with and without short circuit current limiting ...
متن کاملCondition monitoring methods, failure identification and analysis for Induction machines
Induction motors are a critical component of many industrial processes and are frequently integrated in commercially available equipment and industrial processes. The studies of induction motor behavior during abnormal conditions, and the possibility to diagnose different types of faults have been a challenging topic for many electrical machine researchers. The Motor Current Signature Analysis ...
متن کاملFrequency Depended Spectral Subtraction For Speech Enhancement
The corruption of speech due to presence of additive background noise causes severe difficulties in various communications environments. This paper addresses the problem of reduction of additive background noise in speech. The proposed approach is a frequency dependent speech enhancement method based on the proven spectral subtraction method. Most implementations and variations of the basic spe...
متن کاملCondition Monitoring of Rotating Machinery using Active Magnetic Bearings
The concept that changes in the dynamic behaviour of a rotor could be used for general fault detection and monitoring is well established. Current methods rely on the response of the machine to unbalance excitation and are mainly based on pattern recognition approaches. However these methods are relatively insensitive and the crack must be large before it can be robustly detected. Active magnet...
متن کاملReal-time on-board condition monitoring of train axle bearings
Premature failure of rail axle bearings causes a significant increase in train operating costs and can impact train safety. A new on-board condition monitoring approach provided by Perpetuum Ltd is fitted on passenger trains to provide the operator with real-time information on bearing health. This new technology allows the detection of early bearing damage. This paper reports an initial study ...
