The Westinghouse all brass brushed fan motor has non conductive brush caps, yet it runs just fine. How does it operate without conductive cap threading and conductive contact with the spring?

How does the ornate base Diehl DC fan motor run with brush caps machined completely from non-conductive material.

Mr. Nordin, being your PM to me expresses your doubts in my knowledge and experience, please bring your questions to the forum in the future where your chances are higher for a competent answer.  I barely got through high school. Fact Jack.

Russ would the brush cap have to be grounded?
If the spring out of the brush touches  a ground    would the cap have to be grounded?

The reason the ornate Diehl and Westinghouse all brass will operated with nothing conductive on the cap is because the wiring to the individual brush holders is internal. The circuit is carried from commutator to brush to conductive brush holder to internal wire connection. 


The R&M list 3600 & 3000 universal motors brush holders are wire connected internally to the conductive brush holders it appears.  If so......it should be possible to replace these R&M list AC/DC fan motor original brush caps with brass threading with a nylon threaded brush cap without effecting function.  Someone please correct me if I am wrong as I have not restored one of these ......yet.

If the brush cap is non-conductive such as a all brass Westy, its only purpose is to contain the brush compression spring.

The Staghorn would be an example of a conductive brush cap and EXTERNAL wiring to the brush/brushholder.

I would suppose that the brush spring or the brush itself would touch the conductive side walls of the brush holder at some point, providing enough contact to transfer power. Right?

Notice the machined Diehl composite brush cap is completely non-conductive, the only way the juice can be transferred is through carbon brush/spring contact with the conductive brass brush holder.

Tom, I can't decide if I love that avatar or find it disturbing. It does put a smirk on my face when I see it though!

If you need brush caps, Darryl has a bunch of them. I have them on my all brass Westys.


This will probably disturb you....

or this



I seriously hope these are just gag photos.....

cheers,
Bill

Brush caps aside... why are brushes sometimes shunted?

Emerson DC ball motor..shunted
Northwind ... unshunted.
