uses a tachometer for speed feedback
uses a variable dc voltage for speed control
can provide precise position control
All of the above E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is D. All of the above.
A DC servo motor is a type of electric motor that uses a DC voltage to control its speed and position. It has a built-in tachometer that provides feedback on the motor’s speed, and a controller that uses this feedback to adjust the motor’s speed and position. This allows the motor to be used in applications that require precise control, such as in robotics and machine tools.
Here is a brief explanation of each option:
- Option A: A DC servo motor uses a tachometer for speed feedback. The tachometer is a device that measures the speed of the motor’s rotation. This information is used by the controller to adjust the motor’s speed so that it stays at the desired level.
- Option B: A DC servo motor uses a variable DC voltage for speed control. The controller can adjust the voltage that is applied to the motor, which changes the motor’s speed. This allows the motor to be operated at a variety of speeds, depending on the application.
- Option C: A DC servo motor can provide precise position control. The controller can use the feedback from the tachometer to determine the motor’s position. This information is used to adjust the motor’s speed and position so that it stays at the desired location.
