Product description

The Siemens 1FT6134-6SF71-4EL4 is a SIMOTICS S synchronous servo motor delivering 140 Nm of torque at 3000 rpm. It features force ventilation and an ENDAT 2048 P/Rev absolute encoder, providing high-precision position feedback. This motor is designed for IM B5 mounting with an axial drive end, a plain shaft, and a gamma sealing ring for IP65 protection. Note that the absolute encoder causes a 10% performance reduction.

This motor is engineered for advanced automation applications demanding exact positioning, such as in high-precision machine tools, automated assembly, and robotics. Industries including aerospace, medical device manufacturing, and semiconductor fabrication can leverage its capabilities.

Stanlo Automation, a veteran-owned surplus distributor, provides access to this Siemens 1FT6134-6SF71-4EL4 motor. We focus on delivering dependable surplus automation parts to minimize downtime and optimize operational costs for our clients.

Frequently asked questions

What is the advantage of the absolute encoder in the Siemens 1FT6134-6SF71-4EL4 motor?

The ENDAT absolute encoder on the 1FT6134-6SF71-4EL4 motor provides precise position information without needing a reference run after power loss. This significantly improves startup times and accuracy in dynamic applications, though it results in a 10% performance reduction.
