A Thermolite electric insulating system of heat resistance classes H and C is tested and the test results are presented. It is shown that the developed insulating system makes it possible to increase the motor's power compared to traditional systems.
An examination was made of the theoretical principles of the process of pressing glass-fabric laminates. The main factors influencing the process and the quality of the material obtained were determined. The influence of the properties of the binder on the production of a stable, dipped glass fabric was studied. On the basis of the experimental work carried out, the optimum conditions for the processes of dipping and pressing glass-fabric laminates were determined. The results of the work have been used on new equipment introduced at the "Elektroizolit" CJSC. A considerable saving of energy resources and solvents has been achieved.
A brief review is given of insulating systems for electric machines and impregnating compounds as one of the key insulating components is given. Possibilities of producing and processing various types of domestic compounds are considered. Properties of glass mica tapes that contain an impregnating compound for cohesion are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
