Motor Rewinding Procedures

Alternating current (AC) and direct current (DC) motors employ an insulated, current-carrying coil essential to their operation. The traditional method for motor rewinding involves removing the old coil, winding a new coil and varnishing.

Old coils are removed by heating the stationary part of the motor (stator) in an oven. The stator is kept in the oven at temperature of 343 degrees Celsius for at least 10 hours or until the winding insulation turns to ash.


New coils are traditionally wound by hand by a technician on a coil winding machine. The technician controls the wire tension, layering and number of turns on the coil, although there is also a mechanical counter on the machine.


The newly rewound coil is warmed in an oven, immersed in an epoxy varnish and baked in an oven at a temperature of 149 degrees Celsius for at least four hours. This procedure is known as dip and bake.
