Servo Amplifiers — New & Used

Servo amplifiers (or servo drives) regulate power delivery between a controller and a servo motor, ensuring precise torque, speed, and position control in automation and motion systems. Designed for high-performance feedback and accurate motion synchronization, servo amplifiers are essential in robotics, CNC machinery, packaging, and automated assembly lines. Available in both analog and digital models, they provide seamless integration with PLCs and motion controllers.
