If the terminals of armature of D.C. motor are interchanged, this action will offer following kind of braking?
Correct answer: B. plugging
- A. regenerative
- B. plugging
- C. dynamic braking
- D. none of the above
- E. any of the above
Explanation
Reversing the armature connections while keeping the field connections unchanged reverses the electromagnetic torque against the existing rotation. This produces plugging, also called reverse-current braking.
