Abstract :
Thermal aging studies were conducted on four encapsulated insulation systems on motorettes to establish their thermal rating. Encapsulation of Class-A and class-B insulation systems was found to upgrade a Class-A system from 105 to 138°C and a Class-B system from 130 to greater than 150°C. The effect of thermal shock on the thermal life is demonstrated to reduce the thermal life by a factor of 10.
