It is generally known that the most common reason for replacing rotary electric machines is failure of field windings. Vibrations and primary overheating of field windings is the main reason for motor and generator repair. Consequently field windings have been fan cooled, externally ventilated, and totally enclosed. To solve this failure problem stators have been completely encapsulated, drip coated, and entirely coated. But all of these procedures are subject to certain disadvantages. The method and apparatus herein overcome such disadvantages. Apparatus is provided for embedding in a solid material field windings of stators of rotary electric machines in order to insulate and cool electric machines in which the stators are employed.
