Q. Which of the following is correct formula for braking torque in plugging?

(A) n (ka2/rb)
(B) n2 (ka2/rb)
(C) n-1 (ka2/rb)
(D) (ka2/rb)

💬 Discuss

✅ Correct Answer: (A) n (ka2/rb)

Explanation: braking torque is equal to braking power divided by speed of the motor. t= [(nka )2/rb]/n. as, braking power is equal to ea2/rb/n. by solving for the braking torque from the above equation, we get n (ka2/rb).
