Servomotor or control motor is a type of electric motor that is designed to be used in feedback control systems. Inertia is low in these motors and as a result the speed change in these motors is very fast. Usually the diameter of these motors is small but their length is large
Servo motor application
Wherever the majority of electric motors can be used, a variety of servomotors can also be used. The price of this type of device is high, so where we need high accuracy, high speed and fast response, this type of electric motor is mostly used. This type of electric motor has been widely used in metal CNC machines, wood CNC machines, gold medical machines, plastic injection machines, printing machines, electronic parts production machines, and textiles.
The difference between servomotors and step motors
More nominal power
More application in industry
Uniform period (low torque ripple)
Having an electronic feedback circuit commonly seen on the motor.
Having a separate power cable from the signaling cable (Kinetics)
Ability to adjust angle, angular velocity and angular acceleration
Different types of electric motors, such as DC brushless motors or induction motors
