Siemens 1FK7105-2AC71-1QA0 SIMOTICS S 1FK7-CT 48 Nm 2000 rpm Servo Motor

The Siemens 1FK7105-2AC71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated at 7.7 kW with a 48 Nm standstill torque at 2000 rpm nominal speed. It runs from a 600 V DC bus, mounts in IM B5 (IM V1, IM V3) configuration with Flange 1, and carries a Drive-CLiQ absolute single-turn 20-bit encoder (AS20DQI) with IP64 protection and no holding brake.

Technical Specifications

Selection Notes

This frame delivers 48 Nm standstill torque at 7.7 kW, more continuous torque and power than a smaller frame size in the same servo motor series, for axes that need more continuous torque at the same 2000 rpm nominal speed. Without a holding brake, the servo drive or an external brake must hold the axis at standstill; the same frame is also offered with an integrated brake for vertical or overhung-load axes. At 154.000 kgcm2 moment of inertia and a 125,000 Nm/rad shaft torsional stiffness, this motor suits higher-inertia loads than a smaller frame size in the series.
