Which of the following load normally needs starting torque more than the rated torque?
Correct answer: B. Conveyors
- A. Blowers
- B. Conveyors
- C. Air compressors
- D. Centrifugal pumps
Explanation
Conveyors often require high starting torque because the motor must overcome static friction and start a loaded belt. Blowers and centrifugal pumps generally have lower starting torque requirements.
