D.C. servomotors are used in______________?
Correct answer: A. purely D.C. control systems
- A. purely D.C. control systems
- B. purely AC. control systems
- C. both D.C. and AC. control systems
- D. none of the above
Explanation
A DC servomotor is designed for systems in which the actuating and control signals are DC, whereas AC servomotors are used for AC control arrangements. Its torque and speed are conveniently controlled by varying the armature voltage.
