A tachometer is added to servomechanism because:
A. It is easily adjustable
B. It can adjust damping
C. It reduces steady state error
D. It converts velocity of the shaft to a proportional Dc voltage
Answer:B
A tachometer is added to servomechanism because:
A. It is easily adjustable B. It can adjust damping C. It reduces steady state error D. It converts velocity of the shaft to a proportional Dc voltage
Explanation: A tachometer is a device to control the speed and adjust damping and it is used in servomechanism to adjust damping and mainly is used in AC servomotors.
