Servo Motor & Driver (Servo)

Product Specifications

Technical details and manufacturing context for Servo Motor & Driver (Servo)

Definition

The Servo Motor & Driver (Servo) is the core electromechanical component of a Pneumatic/Servo Actuator system. It provides the controlled rotational force and motion. The driver receives command signals (e.g., from a PLC), processes them, and delivers precisely controlled power to the servo motor, enabling high-accuracy positioning, velocity regulation, and torque output for the actuator's mechanical function. This product is a component intended for integration into larger machinery. It is not a standalone machine. The system operates on a closed-loop control principle, ensuring precise motion. The motor typically uses permanent magnets (Neodymium) and is driven by a dedicated electronic driver. The driver contains a printed circuit board and power electronics. The housing is typically aluminum alloy for heat dissipation. The motor laminations are made of electrical steel, and windings are copper. Connectors and insulation use thermoplastics. The product is available in a range of rated powers from 0.1 to 7.5 kW, rated torques from 0.32 to 35 N·m, and rated speeds from 1000 to 3000 r/min. Positioning accuracy is ±0.01 mm, and repeatability is ±0.005 mm. Input voltage is 220–480 V AC, and control signal is 0–10 V DC. Operating temperature range is -10 to 40°C. Protection class ranges from IP54 to IP65 per IEC 60529, and insulation class is F per IEC 60085. Weight ranges from 2 to 50 kg, and dimensions vary from 100×100×200 mm to 300×300×500 mm. These values are reference ranges; actual specifications must be confirmed with the manufacturer for the specific model and application. The product is not certified or compliant with any standards unless explicitly verified. Always consult the legal manufacturer or supplier for model-specific values and standards.

Working Principle

The system operates on a closed-loop control principle. 1) A command signal (desired position/speed) is sent to the driver. 2) The driver amplifies and modulates power to the servo motor. 3) The motor rotates, and a built-in encoder (or resolver) constantly feeds back the actual position/speed to the driver. 4) The driver compares the feedback with the command, calculates any error, and adjusts the power output to the motor in real-time to minimize this error, achieving precise motion control.
