Kollmorgen 6SM57S-3.000-G Product Details

Product Model: 6SM57S-3.000-G (Standard form: 6SM57S-3000-G)

Brand: Kollmorgen / Seidel

Product Series: 6SM Series Synchronous Servo Motor

Product Category: Three-phase Permanent Magnet Synchronous Servo Motor (with Brake)

Compatible Drives: SERVOSTAR 600/400/300 Series (S6, S4, S3 Drives) 

I. Product Overview

6SM57S-3.000-G is a low-power, high-dynamic, and brake-equipped (brake-on) synchronous servo motor in the 6SM series of Kolmorgen (formerly Seidel). Compared to the 6SM57M model in the same series, this model has smaller inertia and lower torque specifications, making it more suitable for precise positioning scenarios requiring high speed, light load, and rapid start-stop. The model suffix -G indicates the integration of 24 VDC electromagnetic brake-on, which automatically locks the shaft when power is lost to prevent the load from sliding, and is suitable for safety-critical applications such as vertical axes, robot joints, and gantry mechanisms.
