  • Description

The Siemens 1FK7081-2AH71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 1.8 kW with 12 Nm standstill torque at 100K and a 4,500 rpm rated speed. It runs on a 600 V DC link, mounts as IMB5 with a rotatable power connector, and carries an IP64 enclosure with an absolute 20-bit single-turn DRIVE-CLiQ encoder. No holding brake.

Selection Notes

Against the 3,000 rpm version of the same 12 Nm frame, this 4,500 rpm winding trades standstill torque headroom for top speed — pick it when the move profile needs higher rapid-traverse velocity rather than sustained torque near zero speed. Weight is essentially unchanged at 12.9 kg, so it drops into the same mechanical envelope without a redesign.
