Lancashire Dynamo, Crypto- Rotary Transformer Converter
Hi all
Was wondering if any of you clever people out there had come across one of these, A Lancashire Dynamo, Crypto- Rotary Transformer Converter. Believe it to be a 110v DC unit from the circuit diagram. Has a date of 1932 on the data plate. the only thing I can find close to it is a Crypto battery charger for charging accumulator cells. Has F, L, A on one set of terminals & S1, S2 on the other set, Myself & a friend have been researching it over the last few weeks & believe F,L,A are the input possibly from a Face Plate starter. S1,S2 to be the output voltage which according to the data plate this is also 110v, It has a commutater at one end of the shaft & slip rings at the other, which strangely are cast iron. There are a few odd things with the data plate .-
1, The makers name has been scratched off (Lancashire Dynamo & Crypto joined together in 1932 possible reason?)
2,On the secondary part of the plate it has 50 PER ,cant find out what PER means is it like Hz ie the 50.
Look forward to any thoughts you may have on it.
