A motor operates on a periodic duty cycle consisting of a loaded period of 40 min and no load period of 22 min. The maximum temperature rise is 90֩ C. Heating and cooling time constants are 55 and 77 min respectively. When operating continuously on no load the temperature rise is 13֩ C. Determine: a- Minimum temperature during the duty cycle. b- Temperature when the motor is loaded continuously.
