Device for indicating the direction of rotation of a body driven by a rotating electrical machine

Image Number 3 for United States Patent #4001689.

A device for indicating the direction of rotation of a rotating body forming part of or associated with rotating electrical machine comprises the combination of a probe unit positioned to interrupt magnetic lines of force generated by the electrical machine, a detector for interpreting signals from the probe unit, and an indicator, which can be a center zero current meter or an oscilloscope, for displaying direction of rotation.
