Short Circuit

• When a motor burns out, a short circuit occurs in the windings and the motor ceases to turn. You can test for a short circuit by checking the resistance of the windings with an ohmmeter; a reading of 0 ohms (Ω) indicates a short.
  
  

Winding Removal

• The first step in rewinding a motor is to remove the old winding. Commercially, this is done by baking the stationary part of a motor in an oven at 650 degrees Fahrenheit for several hours.
  
  

Rewinding Coils

• The new windings are wound on a coil winding machine, under the supervision of a technician, who controls the tension, layering and number of turns. The newly wound coil is dipped in epoxy varnish and, once again, baked in an oven to complete the process.
