Title: Brush generator
Post by: Steeleye on September 12, 2020, 09:16:55 AM
Hi all .I have a BRUSH generator which produces (I hope) 240vac and 32vdc. I would assume it will need some sort of excitation to be able to work. Can anybody help with a connection diagram ? E9840063 ? Any help appreciated. Regards Phil.

Hi Phil, and welcome. could you give us a bit more to work with please. What was, or is your Brush generator driven by? Does the unit have a starter motor or is it a Start-o-Matic type?

The SOM variants have a starter motor/dynamo built into the generator head. If you look inside you should see a couple of brass slip rings and also a commutator (segmented) ring. These units have a main field, a series field and an auxiliary field.

Does it look like this photo inside?
