Learning Outcomes
The student learns to rate a motor, based on the stresses caused by transient states and is introduced to the warm-up model of a motor and various protection and control devices. The student gets familiar with various ways of start, deceleration and speed control and the selection of a motor and the control of a motor with a frequency converter.
