Default Re: Lancashire Dynamo, Crypto- Rotary Transformer Converter

Fantastic information thank you, Do you think this is to provide an AC out put even though it has +& - shown on the output terminals?
The field windings test ok giving about 60 ohms each, not had chance to test the rest yet still cleaning it up.
Have added couple more pictures one of what we think the internal wiring is and one of what the circuit diagram shows as far as I can tell.
As shown on the first drawing the wires from F and L to the coils have come off (mouse I think) so we don't the polarity of the connections if you have any thoughts.
looking into running it from a 230/110v 3kva transformer through a 150A full bridge rectifier.
hoping to get the slip rings skimmed on a friends lathe. Have you any thoughts on why they might be cast iron slip rings & not brass.

Many thanks,
