As someone who used to buy used industrial electric motors up to 1200 hp with rpm’s from 600 to 3600, I know they can be bought on the salvage market pretty cheap, especially if you do not need it immediately.
I wonder why dyno shops do not have a 3600 rpm electric motor at a horsepower their 220/260 volt 3 phase service maxes out at to use for periodic calibration?
