A servo drive is an electronic amplifier that provides power and control signals to a servo motor. It receives low-power command signals from a controller and amplifies them to deliver the appropriate voltage and current to the motor, enabling precise control of position, velocity, and torque.
The drive operates in a closed-loop system. It compares command signals with feedback from encoders or resolvers on the motor shaft. The error signal is processed by control algorithms (often PID) to adjust the power output, ensuring the motor follows the commanded values accurately.
Key parameters include rated power (0.4–15 kW), rated current (2.5–30 A), peak current (5–60 A), supply voltage (220–480 V AC), control voltage (24 V DC), frequency response (2–3 kHz), speed range (1:5000), and operating temperature (0–55°C). Always verify with the manufacturer.
Typical materials include printed circuit boards (PCBs), semiconductors such as IGBTs or MOSFETs, aluminum heat sinks, capacitors, and inductors. These components are selected for their electrical and thermal performance.
