Abstract : This document describes an elastomeric bore seal, and a method of making andinstalling it. The seal is a fluid-impervious, thin-walled (0.025 inch), open-ended, cylinder-like member which is made of an expansible material that can withstand a wide range of temperatures (-65 F. to +400F.) and that is to be bonded and thereby installed. The use of the seal is a bore seal in an electrical machine not only provides an economical, reliable, leak-proof way of excluding stator cooling fluid from the rotor cavity, but also permits a significant reduction (26%) in the weight of the electrical machine and a correspondingly substantial reduction in the size of the machine itself.
