What Is a Servo Motor & Servo Driver?

Servo motors and servo drivers are precision motion control components that convert electrical control signals into fast, accurate, and repeatable mechanical motion in CNC machines and automation systems. By combining high-resolution feedback, DSP-based control, and optimized drive algorithms, servo systems precisely regulate speed, torque, and position—significantly reducing vibration, preventing step loss, and ensuring stable long-term accuracy compared with traditional stepper drive solutions in demanding CNC applications.
