Alternate drives for Eddy current motors.

[Jamie]

I our location, we still have many eddy current
motor's in use.
This morning, one of them had a minor motor short
that worked it's way to the brake and caused some
high voltage to leak back into the drive causing it to burn up!
if the Motor was properly grounded, this would not have
happened.. in any case, damage was done.

Well, now the next story, we have no more Drives in house, nor
do we have time to fix any... this was a HOT!!!!!!!! machine and
had to be running!... So solution!!...
and they all got a chuckle out of this one.
used a KB regen drive to operate the clutch and brake along
with feed back options..
After a few hours of fast hacking work using a couple of
DIODES to split the signal between the brake and clutch on the
output with a load R on both sides, i had that baby running just
as smooth as it ever did!..
They were not chuckling at me afterwards!..

It's a amazing what a little ingenuity will do for you, when
you're in a jam!

So, you either did, or had, a shoddy installation that was allowed to
fail, then you do a half assed patch and want a pat on the back?
