Rewinding a burnt EM motor winding

Steps

  • Measure one strand of the original winding wire with a micrometer.
  • Find a scrap coil wound with the same wire diameter.
  • Unwind or cut away all of the burnt motor winding.
  • Wind the donor wire onto the motor's laminations; neatness isn't critical.
  • Aim for about 4 ohms total, or match a good motor from the same game if you can measure one.
  • Sand the enamel off the wire ends and solder them to the motor lugs.
