vxo@mattblaze I bet that big chunky handwheel there went to a clutch that engaged or disengaged a separate startup motor that got the AC motor turning before field and rotor current were brought up in a very hands-on, steampunk, seat of the pants, high stakes looking procedure.
I've seen YouTube videos of this...
@mattblaze OH this isn't the video I was looking for yet but hooooooooly moly that's blissful.
Not sure I really call it a classic ASMR response or anything, but this stimulates the good chemicals in my brain.
Watch the initial start-up of a 1915 vintage 750 HP (560 kW) motor #shorts #youtubeshorts

Synchronous motor start 350 HP 2400 volt
@mattblaze oh I forgot, this one doesn't use a pony motor to start it, it just lets the entire housing spin free then gradually load up the output using the brake. It's a hilarious but effective approach. Just let it do a cartoon slipping run (to be accompanied by rapid bongo drumming)
