Siemens 1FK7083-2AC71-1QA0 SIMOTICS S 1FK7-CT 2.6 kW 16 Nm 2000 rpm Servo Motor

The Siemens 1FK7083-2AC71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 2.6 kW with 16 Nm standstill torque at 100K and a 2,000 rpm rated speed. It runs on a 600 V DC link, uses natural cooling, and carries an IP64 enclosure with an absolute 20-bit single-turn DRIVE-CLiQ encoder (AS20DQI). This variant ships without a holding brake.

Technical Specifications

Selection Notes

At 2,000 rpm rated speed this 16 Nm winding is built for torque-dense, lower-speed axes rather than rapid traverse — the 2.13 Nm/A torque constant delivers more torque per amp than the 12 Nm/3,000 rpm winding in the same 1FK7-CT family, at the cost of top speed. The 26.000 kgcm² rotor inertia and 101,000 Nm/rad torsional stiffness suit direct-coupled loads that need stiff, repeatable positioning without a gearbox.

Applications

Typical use: geared or direct-drive axes on machine tools and material-handling stations where 16 Nm standstill torque at moderate speed matches the load better than a high-speed winding.
