I've tried looked on google for some resources on replacing the windings but didn't find much. Are you aware of any?
I would like to salvage this old motor. It's not about profit, but keeping something alive that has been around for over 60 years already
I can understand that. I've done a few motors just for the fun of it.
The best book available on electric motor repair that I'm aware of is "Electric Motor Repair" by Robert Rosenberg and August Hand.
Many of the supplies you'll require, such as the right magnet wire, varnish, lead wire, etc. are available from ebay, McMaster and other suppliers. Electric motor rewind shops will also sell materials, such as slot insulation, if you ask nicely. The couple of electric motor rewind shop suppliers I'm aware of sell only in large quantities.
The first hurdle you'll have to jump is stripping out the old windings. This can be accomplished with a bucket of methylene chloride paint stripper. Simply immerse the core in the bucket for several hours, then thoroughly rinse the core and start clipping. It's a tiring process.
Clean the core with a non-conductive abrasive, such as walnut shells.
The slot insulation, such as Mylar Dacron Mylar is easily cut with a good quality paper cutter.
Your next hurdle will be winding the coils. I built a coil winder to handle the task, but a wooden form will work just as well!
Once the coils and phase paper are in, you're ready to add the leads, lace it up and dip it.
There are many catalyzed insulations available today which do not require post-baking.
In the end, it's a lot of work and more expensive than buying a new motor. However, you'll learn a new (and dying) skill which very few people today understand.
