Speed regulation is accomplished by sensing the speed of the motor and____________ .
A)connecting current transformers to the input of the drive
B)feeding this information back to the drive
C)sensing the increase in current as load is added
D)adjusting this speed

Question

Quizplus · Accepted Answer

Speed regulation requires feedback of the actual motor speed back to the drive to enable adjustments to the speed as needed. Option A is incorrect as current transformers are used for monitoring current, not speed. Option C is incorrect as an increase in current may not always indicate a decrease in speed. Option D is incorrect as speed regulation requires adjustments to be made to maintain a constant speed, not just adjusting the speed. Speed regulation involves feeding back the speed information to the drive in order to adjust the speed accordingly. Option A does not explain how the current transformers would regulate the speed, option C is describing how motor load is sensed, and option D repeats the question without providing an explanation.
