To get the speed of D.C, motor below the normal without wastage of electrical energy is used?
Correct answer: A. Ward Leonard control
- A. Ward Leonard control
- B. rheostatic control
- C. any of the above method
- D. none of the above method
Explanation
Ward-Leonard control varies the armature voltage using a motor-generator set, allowing speed reduction with little energy wastage compared with rheostatic control. Rheostatic control dissipates the unused energy as heat in a resistance.
