20 Nm torque 3000 RPM speed Resolver feedback Holding brake Smooth shaft IP64 sealing

The Siemens 1FT6084-8AF71-3TH3 is a SIMOTICS S synchronous servo motor from the 1FT6 series, offering high-speed performance combined with holding capability. It delivers 20 Nm of torque at 3000 RPM, with natural cooling and IM B5 mounting (IM V1, IM V3). This motor features a power and signal connector with axial NDE outlet, a 2-pole resolver (P=1) for feedback, a smooth shaft, circular runout tolerance N, and a holding brake. The motor is protected with a labyrinth seal, offering IP64 rating, and has a vibration severity grade R.

This servo motor is ideal for applications that require rapid movement and the ability to hold position securely when power is removed, such as vertical axis drives in robotics, material handling, or machine tools. Industries include packaging, automation, and manufacturing.
