We built a large 400 hertz power supply for subs back in 1960.
It had to have a certain form factor to get it down through the hatch.
Hi Bushbadee,
Yes, that was one of the requirements of many pieces of submarine
machinery!!! (even the main feed pumps I worked on several different
400 hz sets, perhaps the oldest was 400HZ, 120V 3phase 42kW motor-generator
sets used on the old Permit class (renamed after the Thresher accident in
'63). IIRC, these were all mag-amp units. The only 'electronic' thing in
them was the silicon rectifiers.
