Product Introduction
AC servo motors for industrial automation achieve precise speed, position, and torque control through closed-loop control. They are suitable for production lines, robotics, and handling equipment.
Product Advantages
High-Precision Control
This AC servo motor utilizes a high-resolution optical encoder, achieving motor rotation angle accuracy up to 0.01°.
Fast Response
The servo motor's control system response time is less than 1ms, enabling rapid output adjustments in response to load changes or command changes.
High Overload Capacity
The servo motor can withstand instantaneous overloads up to three times its rated torque and maintain stable operation during equipment startup and acceleration.
