Servo motors and drives are critical in machinery that needs intricate position control, such as conveyor belts, robotics, camera focus, and automation amongst others. Servo Motors can be broadly classified as simple electric motors which are controlled for specific angular rotation with the help of an added servomechanism. They are fundamentally a combination of various electronic parts, including the well-known DC and AC motors.

A servo drive is a basic element of a motion control system which also includes a servo motor, controller, and feedback element. Servo drives take a command signal for position, velocity or current and adjust the voltage and current applied to the servomotor based on closed-loop feedback.
