Technical details and manufacturing context for Driver/Amplifier

Definition
A critical component within servo motor systems that interprets control signals from a motion controller and converts them into high-power electrical currents to precisely operate servo motors. It regulates torque, speed, and position by managing voltage and current to the motor windings, enabling accurate motion control in industrial automation applications.
Working Principle
Receives low-voltage command signals (typically ±10V analog or digital pulses) from a controller, processes these signals through power transistors (IGBTs or MOSFETs), and amplifies them to deliver controlled high-current power to the servo motor. Uses feedback from encoders or resolvers to adjust output in real-time for closed-loop control.
