Product description

The Siemens SIMOTICS S servo motor, model 1FT6102-8AH71-4AL4, is a high-performance synchronous servo motor with a torque of 27 Nm and a maximum speed of 4500 RPM. It features natural cooling, IM B5 mounting (IM V1, IM V3), and an IP65 protection rating from its Gamma sealing ring. This specific model includes a holding brake and is rated with Vibration Severity Grade R. It is equipped with an incremental encoder (sin/cos 1 Vss 2048 S/R) and has an axial DE (Drive End) connector outlet.

This motor is engineered for high-dynamic applications demanding precision, speed, and robust load-holding capabilities, such as advanced robotics, automated manufacturing, and machine tools. The 'R' grade for circular runout tolerance and vibration severity indicates a higher standard for mechanical precision and operational smoothness.
