Siemens 1FK7060-2AF71-1QA0 SIMOTICS S 1FK7-CT 1.5kW 6Nm 3000rpm Servo Motor

The Siemens 1FK7060-2AF71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 1.5 kW, 6 Nm standstill torque (M0, 100K), and 3000 rpm rated speed at 600 VDC bus voltage. It is naturally cooled, IMB5-mounted, and fitted with a DRIVE-CLiQ absolute single-turn 20-bit encoder (AS20DQI); this order number ships without a holding brake.

Technical Specifications

Selection Notes

This 1FK7060-2AF71 winding ships without a holding brake, so it fits horizontal or gravity-balanced axes that do not need to hold position when de-energized; the same frame is also offered with a brake for vertical or unbalanced loads. Its 1.33 Nm/A torque constant keeps the 3.7 A rated current low for the 6 Nm standstill torque, and the 40,500 Nm/rad shaft torsional stiffness supports tight positioning loops with a rigid coupling. A higher-speed winding is also available in the same frame at a lower torque constant, trading current efficiency for base speed.

Applications

Natural (fan-less) cooling and IP64 protection suit compact machine enclosures without forced airflow, including light general-purpose axes and environments with incidental dust or washdown contact. The DRIVE-CLiQ interface connects directly to SINAMICS S120/S210 drive systems over a single feedback cable. At 6 Nm standstill torque and 3000 rpm, it fits ball-screw or belt-driven axes in the low-to-mid power range rather than high-speed spindle duty.
