Armature winding lathes
 

I have looked at several lathes that had spent their lives in the shops
of electric motor rebuilders, used solely for winding armatures.
Invariably the ways are rusted, apparently having never been oiled. I'm
talking more rust than a Scotchbrite would handle. Maybe a file.
Is this usually the case, and I need to quit looking at equipment
from electrical rebuilders?

Sometimes the case. Depends on location.

Ive found that in SOME small shops, the rewinders got a lathe that was
clapped out and used it for 20 yrs..so its been clapped out twice.

YMMV of course.

Not really germane to your question, but back when I was in the service (30+
years ago) There was a civilan run shop on one of my duty stations that was
the electric motor shop. The had the most amazing machine I had ever seen. I
was a motor rewinder. It looked like a cross between a lathe, a mill and a
sewing machine. It had spindles for about 20 wire spools and had more cams
and cogs and bellcranks and dohickys than you can imagine with a HUGE book
on how to set it up. One you got it all rigged it would automatically rewind
any size and configuration of field or armature you could imaging. I've
always wondered what happend to that old beast, I'm SURE it was surplussed
years ago..

Always wondered how an armature was wound so neat and tight, considering
the small gap between each section.

Same here, but also I wondered even more how the field windings (on the
inside) were done.

Gunner, how about posting a description of how a machine like this
operated when rewinding an armature?

THe Field is easy. It is wound on a frame and then Bent to fit. Simple as that.
Motor repair places have a Jig that holds 4 fingers that are adjustable and locking.
Rotates and collects wire.

Harry..I dont have a clue on procedures, other than used for
commutator and bearing turning and wire winding. Not my area of
expertise. I have seen the lathes they use, not how they do it.

Ever time I look at the windings of a motor I go cross eyed.
Particularly the ones that have the wire running in bundles through
tunnels in the rotor..thats absolutely fascinating.
