- Description
The Siemens 1FK7105-2AF71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated at 8.2 kW with a 48 Nm standstill torque at 3000 rpm nominal speed. It runs from a 600 V DC bus, mounts in IM B5 (IM V1, IM V3) configuration with Flange 1 and a rotatable power connector, and carries a Drive-CLiQ absolute single-turn 20-bit encoder (AS20DQI) with IP64 protection and no holding brake.

Selection Notes
This AF71 winding is rated for a 3000 rpm nominal speed at 48 Nm standstill torque, a higher-speed option than a lower-speed winding offered in the same 1FK7105 frame, so it fits axes that need faster point-to-point moves at this torque level. Without a holding brake, the servo drive or an external brake must hold the axis at standstill; the same frame is also available with an integrated brake for vertical or overhung-load axes. At 39.001 kg, this is among the larger motors in this product line, so mounting and coupling hardware should be sized accordingly.
