General Motion Control

Product Overview

An AC Servo Motor and Drive System is a high-precision motion control solution that combines a servo motor with a matched servo drive to achieve accurate position, speed, and torque control. Unlike standard AC motors, AC servo motors operate in a closed-loop system, using feedback devices like encoders or resolvers to continuously adjust performance according to control commands.

This combination is widely used in CNC machines, robotics, packaging, printing, automation lines, and material handling systems where precision, repeatability, and dynamic response are critical.

🏭 Common Applications

📌 Product Overview

A Servo Gearbox (also called a servo gear reducer or servo speed reducer) is a precision mechanical transmission device that connects a servo motor to a driven load to modify torque, speed, and motion characteristics. It ensures that the high‑speed, low‑torque output of a servo motor is converted into a lower‑speed, higher‑torque output suitable for mechanical loads, while maintaining smooth, accurate motion and positioning.

Servo gearboxes are widely used in automation, robotics, CNC machinery, packaging, material handling, printing, conveyors, and precision equipment where controlled motion and high positional accuracy are critical.

⚙️ How It Works

A servo gearbox is fitted directly to the servo motor’s output shaft. As the motor shaft spins at high speed, the gearbox uses gear pairs to transmit motion to the load at a reduced speed but increased torque. Because it’s used with servo systems, it’s designed to minimize backlash and maintain positional accuracy.

🧰 Key Features

1. High Torque Multiplication
   ➤ Converts the servo motor’s output into higher torque for heavy or high‑load applications.
2. Speed Reduction
   ➤ Reduces motor speed to match the required speed of the driven mechanism.
3. Low Backlash
   ➤ Designed with precision gears to keep backlash (lost motion) very low, ensuring high‑accuracy positioning — crucial in servo systems.
4. High Rigidity & Precision
   ➤ Precision ground gears and quality materials maintain performance under load and improve motion repeatability.
5. Compact & Robust Construction
   ➤ Engineered for industrial environments with high load capacity and long life.
6. Wide Ratio Range
   ➤ Available in gear ratios from low to high (e.g., 3:1 to 100:1 or more) depending on application requirements.

🔧 Types of Servo Gearboxes 🛠️ 1. Planetary Gearbox

• Most common type used with servo motors.
• Helical or spur planetary gears provide high torque and high stiffness.
• Excellent for high‑precision and compact spaces.

🛠️ 2. Harmonic (Strain Wave) Gearbox

• Features very low backlash and high accuracy — ideal for robotics and precision motion.
• Typically lighter and more compact than planetary gearboxes.

🛠️ 3. Cycloidal Gearbox

• Robust design with shock‑load resistance and high reduction ratios in a compact size.
• Good for heavy‑duty applications.
