ABSTRACT:
An insulated field pole coil assembly for a dynamoelectric machine characterized by including an open-weave glass tape wound in half-lapped fashion around the energizing coil of magnet wire on the pole and coated with a continuous, void-free, crack-resistant dipping compound that is supported by the strands of the tape. In the method of the invention a coil is wound with lapped open-weave tape and immersed in dipping compound which is supported by the tape strands while the compound is cured, and thereafter, to form a crack-resistant, continuous insulating coating around the coil.
