Re: loosing steps & max stepper voltage >30x??.

That brings up an interesting point. I've heard that the
voltage spec is not as important as the current spec.
And I've seen the voltage spec exceeded by >25x in Bridgeport
Nema42 type steppers. As for the winding insulation in these
steppers, I'm ( reasonably) confident they can handle 80+ volts for
the limited on time needed till current tripping at Imax.
( many 120vac appliance motors are wound with regular (laquer/varnish)
coated wire, so I would guess the limiting factor is one of
heat( avg power dissaption) in the coils, and possible degradation of
the insulation by hot spots. Number of turns, inductance, and voltage
per turn comes into play...

Not a motor expert... but heck I'll try to learn anything :-)
