Re: Lancashire Dynamo, Crypto- Rotary Transformer Converter
One and the same. Eventually swallowed by AEI.
Here are two similar small rotary converters in our collection. These both came from a house on an estate with its own 230V DC hydro installation dating from the early 1930s. Most loads in the house (heating, lighting & cooking) were DC, but at some point converter No. 1 was installed for loads that were AC-only. The output is 230V AC single-phase 50Hz at 1kVA continuous rating.
Converter No.2 is from the same house, where it used to power the American refrigeration unit in a larder fridge, hence the output is 115V 60Hz at around 750VA. It was controlled by the fridge thermostat so that it only ran when there was demand for the compressor.
