[ARC5] Bendix Motor Generator

[Andy Young]

Hi Scott,

Ironically what I really need is something to generate 80v at twice the 
frequency, 1600Hz, to supply WW2-era UK equipment such as GEE or H2S!

On aircraft such as the Lancaster that was generated by an engine-driven AC 
generator rather than a Motor-Generator. I do have an example (Generator 
Type UKX) which I plan to drive with a mains-supplied electric motor.

Andy
