I was going to make this My Very Last Stupid Act, but maybe I'll pass and do

I *still* want a big motor, tho....

Yeah, the point about such a big motor on a press is interesting. I think,
in this case, the flywheels are SO big, that considerable hp is needed to
get them started. After that, rel. low hp would keep it going.
Mebbe it's just a *really big* 3 hp motor!!

Does this motor have a commutator on it? A lot of these big, old
presses, shears and such had motors with wound rotor resistance start
systems or centrifugal resistance starting. They have a 16' shear at
the metals supplier that I go to. They shut it off when they go to
lunch, probably to prevent customers from chopping themselves in half.
When they get back from lunch, they turn it back on and let it run the
rest of the day. It must take 45 seconds, at the minimum, for the motor
to bring the flywheel back up to speed. That one has an automatic
resistance starting system. it would burn the motor up for sure if it
was a standard induction motor.
