Abstract
A non-invasive apparatus and method for measuring the speed of a rotating device that includes a sensor that measures a dynamic characteristic of the rotating device. A sample of the signal is transformed from the time domain into a frequency spectrum. The frequency spectrum is then analyzed to determine the motor speed. The resulting motor speed can be combined with other motor data by an order analysis to identify malfunctioning or improperly installed components.
