A novel method for evaluating high temperature mechanical and thermal properties of laminated thermosetting insulating plastics

Abstract

For some time the question of how to choose effectively the proper insulating material for use in electric motors and generators as a stress member has been bandied about by many different people. This problem becomes increasingly more difficult when high temperatures and stresses are encountered particularly when said item is used as a restraining wedge in what is popularly called an open slot armature.
