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)

✅ 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).
