ABSTRACT:
The coils on dynamo-electric machine parts (such as electric motor armatures or stators) are stabilized and coated by electrostatically coating them with resin powder, and then fusing the powder into a continuous resin coating on the coils. For example, the powder may be fused by heat generated by briefly passing a relatively large electrical current through the coils. If desired, the coils may be formed with wire which has an outer layer of bonding material. Activation of the bonding material, which may occur simultaneously with fusing of the resin powder, bonds adjacent coil wires together.
