Abstract

A grounding rope assembly 20 for electrically grounding a rotatable conductive shaft 4 of a dynamo-electric machine. The assembly 20 includes a grounding rope member 40 including a plurality of conductive wires 41 extending along the length of the grounding rope member 40 and one or more discrete fixation points 43 intermediate the first and second ends 42, 44 of the grounding rope member 40. The assembly 20 further includes a rope guide 50 configured to guide the rope member 40 on an electrically conductive surface 6 of the rotatable shaft 4. Two or more of the plurality of conductive wires 41 are affixed together at each of the discrete fixation points 43.

Description

technical field [0001] The present disclosure relates to a grounding device comprising a grounding rope and a guide for holding the grounding rope against a rotating mechanism of an electric machine. More specifically, the present disclosure relates to a grounding rope for grounding a conductive surface of a rotating shaft of an electric machine. Background technique [0002] In many electromotive devices, such as generators and motors, stray voltages can build up on various components of the electromotive device, which can adversely affect and shorten service life of the electric device. In order to prevent current from passing through these components, the various components of the electric device can be grounded with a grounding device. Such grounding devices include grounding brushes, grounding straps, grounding ropes, and other grounding devices for grounding the rotating shaft of a motorized device. [0003] Accordingly, there is a need to provide alternative shaft ...
