An electric motor with built-in position feedback that can precisely control angular position, velocity, and torque. The most common actuator type in industrial and collaborative robotics.
A motor that knows exactly where it is. Unlike a regular motor that just spins, a servo motor constantly checks its position and adjusts to stay precisely where you told it to be. It's the precision athlete of the motor world.
Why It Matters
Servo motors are the backbone of modern robotics. They provide the precise, repeatable motion needed for everything from CNC machining to robot arm control. With China producing over 50% of global industrial robots, the domestic servo motor market is one of the fastest-growing segments in the country's manufacturing supply chain.
Real-World Examples
- AC servo motors in each joint of a 6-axis cobot for smooth, precise movement
- High-torque servo motors in humanoid robot hip and knee joints for walking
- Micro servos controlling the fingers of a dexterous robot hand
China's servo motor market is dominated by Japanese brands (Yaskawa, Panasonic, Mitsubishi), but domestic players are gaining rapidly. Inovance Technology (Shenzhen) is now the #1 Chinese servo manufacturer, capturing over 10% of the domestic market. The government's push for supply chain independence is accelerating investment in domestic servo technology.
