Mike,
Did they put a new coil on the core, or just rewind the old coil? Sometimes, if
the secondary is on the outside of the coil, and it is bad but the primary
good, you can do a partial rewind. I prefer to have a whole new coil myself,
but some do offer this. Where it saves at is both the iron, the engineering
involved in calculating the size, and the number of turns. That is actually how
we learned winding transformers. Folks would bring in bad ones which we
disassembled and rewound. Our instructor though made us calculate everything
instead of just counting what we had. We did motors the same way. The worst
part was taking them outside and setting them on a fire to burn out the
varnised in windings. It was a messy job, but was the way we done them on both
motors and transformers. I really wouldn't recommend this on either because it
messes with the annealing of the iron, and can warp a motor frame out of round.
A home builder might do it, but it would be a big no-no for a comme
rcial product.
Best,
Will
