Model dynamo drawings

[Dougie SwanParticipant @dougieswan43463]

Hi

I just got a set of castings for a model dynamo but it didn’t come with any drawings

It’s 3″ internal dia and about 5 inches long, 3 castings in total

I can’t find anything on line so wondered if the collective knowledge on the forum might be able to help

Thanks

Post a picture of what you have. Easy option tends to be to find a suitable motor and rip the totating bits out of that then wind your own coils and make the bearings and brushes to suit. That is how the Alyn one is done using a Lucus starter motor.

Do you have any idea of it’s perantage as to whether it was a commercial kit or just a spare set soemone ran off. The like sof Stevens Model Dockyard used to sell castings as well as several other sources.

I think I have some more details of this one that could be scaled up if that is the style you have

Very early editions of ME ( the first few volumes )had numerous designs for dynamos though may be not much help in this case they are interesting.  Noel.

Plenty of room inside for a 760 size motor.

Or bigger. I think we need to see the castings first as if it were an enclose circular type a bit like the Stuart then you can just put the whole can and magnets in. If more like the one I showed above then you would most likely want to wind your own so the can and magnets don’t get used and you just use the smaller diameter rotating parts and would therefore have room to base it on a larger motor
