Evaluation and comparison of various weatherproof-chemical resistant insulation systems for pre-insulated form-wound motor field coils

摘要

The need for weatherproof-chemical resistant insulation systems for form wound pre-insulated motor field coils has received greater emphasis in recent years. This has been due partially to the desire to use lower cost open-frame motor designs and to the advent of new electrical insulating materials capable of withstanding moist and corrosive environments.
