New insulation material and process for electric motor repair

Abstract

New materials are at engineers' disposal, which make electric motor rewinds easier and better than in the past. The material is stronger and has a higher density. In this paper, the author discusses Nomex Type 414, Nomex Type 411, FiberTek Res-I-Flex, Surge Rope and Thermaleze Wire, which are all excellent examples of products that provide for a more reliable repair. Using these products has helped to streamline the repair by eliminating steps of the repair process. For example, you do not have to use reinforcement tape on the edges to keep the slot papers from splitting. The wedges are also stronger allowing them to be pushed into the full slot without buckling. It is advantages such as these that encourage the use and continual development of new materials.
