Commercially, this is done by baking the stationary part of a motor in an oven at Six hundred fifty 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.When a Engine burns away, 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 Zero ohms (Ω) indicates a short.
Winding Removal
The first step in rewinding a motor is to remove the old winding.Provided an electric Engine operates at extremely aerial a voltage, excess now flowing complete the windings can explanation them to come fevered and burn gone. While it is usually not practical to repair bitty, frank ongoing (DC) motors that hog burned outside, other motors can be repaired by rewinding.
Short Circuit
The newly wound coil is dipped in epoxy varnish and, once again, baked in an oven to complete the process.
