Default OT? armature question (rotary inverter)


"Don Young" wrote in message
...

My opinion is that the blobs are to reinforce repaired windings. It
would

seem pretty unusual to balance this way since you would have to let the
epoxy harden and then retry the balance. Balancing of armatures is
normally done by shallow drilling the rotor.

Actually, I think its pretty academic. A good motor shop can test the
armature and if it is good, then use it. I am curious what kind of circuit
board would have been removed, the wires crimped, and the unit still
operate. If you can obtain the circuit diagram a handy electronics guy
should be able to build a replacement.

thanks Don,
i'm wanting to take the armature to an electric motor shop, i just want
to be able to walk in the door with some info of my own.
the circuit board, yeah, me too, i don't really know if this thing ran
well or at all. bought it from eBay, auction info said "as is" and "works
good". in a previous post i said one of the carbon brushes was completely
out/gone and the steel spring was rubbing against the slip ring, so, i
suppose it COULD'VE worked but i'm doubting if it worked good. i don't
really know if it worked at all without the circuit board and with the wires
crimped, i didn't try it when i got it, i thought i ought to open it up
first and check it out before i tried to run it. that would be the coolest,
if i could somehow home-build a replacement circuit board (instead of
coughing up the $230 or $400 they're asking for replacement parts).

thanks again.

b.w.
