Performance characteristics of improved solventless silicone resins

Today´s trend in electrical equipment design is toward higher ratings and high capability with minimal increase in physical size or volume of the equipment. Inherent in this trend is an increase in operating temperatures. Temperatures can be reduced by using cooling passageways through which liquid or compressed gas is passed. An alternative is the use of thin walled void free insulation of high thermal capability. In the case of small and medium sized motors used in applications of widely varying loads, such as traction motors, the second alternative offers greater economy.
