Abstract :
Motors are today required to operate in more severe environments than formerly. This paper reports a study of suitable test methods for evaluating the ability of insulation systems to withstand moisture exposure as thermal aging progresses. A new motorette exposure cycle has been recommended to the IEEE Working Group on Sealed Insulation Systems of the Rotating Machinery Committee.
