KOLLMORGEN S21260-SRS Servo Motor
1. Product Description
The KOLLMORGEN S21260-SRS is a high-performance servo motor designed for precision motion control in industrial automation. It’s mainly used to provide stable, accurate rotational power to equipment like robotic arms, precision machine tools, packaging machines, and automated assembly lines—common in automotive manufacturing, electronics production, and aerospace component machining.
With a rugged, compact design, it fits into tight equipment spaces and withstands typical industrial conditions (such as mild vibration, dust, and temperature changes). It delivers consistent torque and speed, enabling smooth motion control for tasks that require high precision (e.g., aligning small electronic parts or cutting complex metal shapes). It’s fully compatible with KOLLMORGEN’s servo drives and most third-party industrial controllers, making it easy to integrate into new or existing automation systems.

3. System Introduction
The S21260-SRS is a key part of KOLLMORGEN’s “S-Series Servo System”—a modular lineup that combines servo motors, servo drives, and configuration software to deliver precise motion control for industrial applications. This system works as a unified unit: the servo drive receives control signals from an industrial controller, sends power to the S21260-SRS motor to drive motion, and uses the motor’s built-in encoder to collect real-time position/speed data for adjustment.
In the system, the S21260-SRS acts as the “power executor”: it converts electrical energy from the servo drive into mechanical motion, following the drive’s commands to adjust speed, torque, or position. The system’s closed-loop feedback ensures minimal motion error, which is critical for applications where even small deviations could affect product quality (e.g., electronic component assembly). This system is widely trusted in industries that require high-precision, reliable motion control.
