shaft grounding with a flat cable

shaft grounding with a flat cable

shaft grounding with a flat cable

(OP)
I saw a large machine which had the shaft grounded using a flat braided steel cable looped once loosely around the shaft with both ends bolted to the machine frame.  (a script lower case "l" shape)

Has anyone ever seen this?  Seems a lot easier than a brush, as long as it works.

RE: shaft grounding with a flat cable

(OP)
This one was just a flat wire braid cable with a lug on each end.  The lugs were used to attach to the frame. The cable itself acted like a brush.  I have a photo I can attach in a few days.

A no-fuzz solution. Pun (even if hard to detect) intended.

There is a forum for shaft grounding, forum1119

RE: shaft grounding with a flat cable

Hi ePete,

We've experimented with similar designs using copper braid. Reasonably effective, but maintenance-heavy. The braid accumulates all manner of crud - presumably oil mixed with dirt - which arguably reduces its effectiveness, and wear means that replacement is required reasonably frequently. Never considered using steel - one to explore perhaps.

If we learn from our mistakes,
I'm getting a great education!

RE: shaft grounding with a flat cable

We Use copper braid on our generators normally 2 per shaft, some have springs attached to the free ends to make sure there is good contact.  It is considered an upgrade from carbon brushes which need to be replaced more often and also collect "all manner of crud" as ScottyUK mentioned.
