Product description

The Siemens 1FT6084-8AF71-3TA0 is a SIMOTICS S synchronous servo motor from the 1FT6 series, designed for robust and reliable operation at high speeds. It delivers 20 Nm of torque at 3000 RPM, featuring natural cooling and an IM B5 mounting (IM V1, IM V3). This motor is equipped with a power and signal connector with axial NDE outlet, a 2-pole resolver (P=1) for feedback, a feather key shaft, circular runout tolerance N, and operates without a holding brake. It is protected by a labyrinth seal, providing IP64 rating.

This servo motor is suitable for applications requiring high speed and reliable feedback, often found in industrial automation, machine tools, and robotics where a resolver is preferred for its robustness in harsh environments. Industries include general manufacturing, material handling, and automation integrators.
