"A motor designed to work on 220 VAC 400 Hz, just don't work right when ya give it 120 VAC 60 Hz,"....
OMG - I actually tried that once >,<
Someone traded me a Navy gun turret servo for a box of tubes. I was 14, didn't even THINK of checking the frequency, just the volts, it did two slowwww revs with a BIG hummmm and smoke and fire ensued :-(

Heh, could b worse. I saw the end result of a motor electromagnetically launching its' bearings, armature shaft, and some of the end housing windings thru the wall of a building. He was a newb and didn't know to check if the retaining setscrews were installed on the end plate, he didn't even realized the innards had launched 'cause he was busy trying to put out the flaming remains of the motor shell with his suddenly overactive bladder. =+}
The buggers lucky the circuit breaker blew. =+DEmpty words of adulation and appreciation do not allow an artist to grow. Overly critical and out right attacks on an artists' work are even more damaging.-
OUCH!!!! D:
I had a far less spectacular, but similar lesson on "Why letting series-wound DC motors freerun with no load is a bad idea!" >,<I like mah gals like mah blueberries - the plump ones are the sweetest ^v^-
LOL! An instructor in one of my very first tech school classes did that, good thing it was a small one hooked up to a car battery. Still an interesting show to see the instructor dive for cover once he realized his mistake. =+}Empty words of adulation and appreciation do not allow an artist to grow.
