The symptoms are pretty clear now. It helped that I recently bought a new Motor and noticed it turns much more voluntarily than my old motor and one I bought used...
I wonder this might effect only some of the windings - might I be able to only rewind the affected ones? How to find those?
Any ideas welcome, other than buy a new motor, because I believe 'you don't really own it until you can repair it', so I am working up the faith to learn motor winding!
I also don't want the new motor to go the same way, and I guess the major approaches are:
- Cooling external
- Cooling heat conducting internal (Ferrofluid?)
- Temperature sensing and limiting
- Protecting windings (vacuum infused resin?)
This thread is prepared to eventually migrate into the Wiki, or is it already there?
