Great link electricpete! Furthermore, there are also a few good text books available on the subject of motor repair/rewinding. I can thoroughly recommend “Electric Motor Repair 3rd edition” by Robert Rosenberg (costs around $180 from Amazon). There are also some very good (but very old) digitalized books available for free view on the American Libraries website. The one I linked is an example. Although it was written in 1920 the actual rewinding & connecting methods are still as valid today as they were then. You can view the contents by clicking on “flip view” tab on the left hand side.
