The evaluation of new high temperature resins for motor insulation

There is a demand today for insulation which will give satisfactory service at 180C for periods of up to twenty years or more. Motors and other electrical equipment run hotter as a result of performance requirements placed upon them by the designer. Also, the new high speed transportation, mining, nuclear, and metal working installations are now operating in environments of high temperature and high humidity which place a severe electrical and mechanical stress on the insulation.
