Motor current signature analysis method for diagnosing motor operated devices

摘要: A motor current noise signature analysis method and apparatus for remotely monitoring the operating characteristics of an electric motor-operated device such as a valve. Frequency domain signal techniques are applied to conditioned distinctly identify various parameters driven from signature. The may be recorded compared with subsequent signatures detect abnormalities degradation device. This diagnostic does not require special equipment installed on device, sensing performed at remote control locations, e.g., where devices used in accessible or hostile environments.
