Abstract :
Accelerated aging tests for induction motors with class E electrical insulation were conducted. The testing period exceeded one year and involved elevated temperatures, vibration, humidity, and voltage application. The activation energy of the aging process was estimated to be 0.72 ± 0.08 eV.
