|A.C. Servo Motor||D.C. Servo Motor|
|Low power output of about 0.5 W to 100 W.||Deliver high power output.|
|Efficiency is less about 5 to 20%.||High efficiency.|
|Due to absence of commentator maintenance is less.||Frequent maintenance required due to commentator.|
|Stability problems are less||More problems of stability.|
|No radio frequency noise.||Brushes produce radio frequency noise.|
|Compare to DC servo motor it is relatively stable and smooth operation.||It is Noisy operation.|
|AC amplifier used have no drift.||DC Amplifier used have a drift.
The Moment of inertia is the measure of an object's resistance to changes in its rotation rate. inertia of the load is a key measure for sizing servomotors.
