Armature rewinding

(1/7) > >>

John Rudd:
Is there anyone here versed in the art of rewinding universal motor armatures?

I have an armature that I would  like to rewind, but my experience is virtually non-existant...,

That said, I rewound the field coils for the drill that matches the armature....

I fear it has shorted turns, there is excessive sparking at the comm, the field coils are warming up too as a result I suspect due to excessive current...

Please help... :zap:

Pete.:
I know it might be a daft question but you can't find a suitable donor machine to rob the armature from?

John Rudd:
Pete,
No chance at all, its a vintage Stanley Bridges Wasp from my collection...made around the early 60's I think.

hermetic:
there are a few of the old "Newness" published electrical series that cover armature winding, if you can get your hands on them, I will check out mine tomorrow at the wshop and see if I can find any details, You need the armarture in a jig where it can be rotated or fixed, and several coils of enamelled copper wire of the correct size, fiddly but doable! My grandfather was a coil winder who specialised in armatures, but that is no help now!

Pete.:
This £20 one on ebay no good for a donor?
