Question

the effect of back emf in an armature-controlled dc servomotor is

Answer 1

g I called you back in the

Answer 2

Answer:

It will increase effective motor friction which eventually reducing motor time constants.

Explanation:

The servo motor are allows for precise control for angular position.

• The speed of DC motor is normally controlled by varying the armature voltage.
• It also having wide range of speed control which also plays vital role in friction and reducing time constants.
