1.	Which duty cycle has on load and off-loads period?(a) Intermittent duty(b) Short time duty(c) Continuous duty with constant load(d) Continuous duty with variable loadThe question was posed to me during an interview.This is a very interesting question from Motors Rating and Heating in portion Rating and Heating of Motors of Electric Drives
Answer» The correct option is (a) INTERMITTENT DUTY To explain: Intermittent duty CYCLE has frequent on load and off-loads period. The on-load period and off-loads periods are too short to ACHIEVE steady-state thermal CONDITION.
