  • Description

The Siemens SIMOTICS S 1FK7080-2AF71-1QA0 is a 1FK7-CT synchronous servo motor rated 2.1 kW at 3,000 rpm, delivering 8 Nm standstill torque (M0, 100K) with a 4.4 A rated current and IP64 enclosure. It uses a single-turn 20-bit absolute encoder (DRIVE-CLiQ, AS20DQI) and natural cooling on an IMB5 flange, without a holding brake.

Selection Notes

The 8 Nm standstill torque and 4.4 A rated current place this frame in the mid-power SIMOTICS S 1FK7 range; higher-torque variants in the same 80 mm shaft-height frame draw more current for a given base speed. The 1.52 ms mechanical time constant and 17.50 ms electrical time constant point to a comparatively fast-responding rotor suited to dynamic positioning rather than pure holding duty. Natural cooling and no holding brake mean vertical-axis installations need an external brake or counterbalance to hold position at zero speed.

Applications

Fits SINAMICS S200/S210-class single-axis drives for packaging, robotics, and machine-tool feed axes, where a DRIVE-CLiQ absolute encoder eliminates a separate reference run and IP64 protection tolerates washdown-adjacent environments.
