A servo drive is an electronic device that controls the movement of a motor, typically in applications requiring precise positioning and speed. It receives feedback from sensors to adjust the motor's performance, ensuring accurate control over its motion. This makes servo drives essential in robotics, CNC machines, and automation systems. The main components of a servo drive include a power amplifier, a controller, and feedback devices like encoders. Together, they work to maintain the desired position and speed of the motor, allowing for smooth and efficient operation in various industrial and commercial applications.
