Servo Drive

A servo drive is an electronic amplifier that controls a servo motor by precisely regulating its position, velocity, and torque based on command signals and feedback. Servo drives enable the accurate, responsive motion required for robotics, CNC machines, and high-performance automated equipment.

A servo drive receives motion commands from a controller and continuously adjusts current to the motor while reading feedback from an encoder or resolver, closing position and velocity loops at high speed. This closed-loop operation delivers tight following accuracy and fast settling. Servo drives matter because demanding applications like pick-and-place, machining, packaging, and coordinated multi-axis motion require precise, dynamic control that simple open-loop drives cannot provide, making them central to modern motion control systems.
