• Stripping the Windings: This involves heating the stator core to soften the varnish and removing the old copper coils. Rosenberg details the risks here: overheating the stator laminations can destroy their magnetic properties, ruining the motor’s efficiency.
• Data Collection: The text insists on recording "winding data" before the old coils are gone—wire gauge, number of turns, coil span, and connection diagrams (wye vs. delta).
• Insertion and Connection: The manual process of inserting new coils into the stator slots, using slot liners for insulation, and connecting the leads to the terminal board is described with surgical precision.
• Varnishing and Baking: The final step to secure the windings, improve heat dissipation, and protect against vibration and moisture.
