Product description

The Siemens SIMOTICS S 1FT6108-8AF71-1EH0 is a high-performance synchronous servo motor engineered for precision automation. This naturally cooled motor offers 70 Nm of torque at 3000 rpm, with an IM B5 mounting configuration. It is equipped with an EnDat absolute encoder (2048 S/R) for exact position data, and includes a holding brake. A 10% derating is applied due to the absolute encoder.

This servo motor is well-suited for complex automation tasks requiring absolute positioning, such as advanced robotics, machine tools, and high-precision assembly lines. Its IP64 sealing provides protection against dust and water ingress, ensuring operational reliability.
