Siemens 1FK7062-2AC71-1QA0 SIMOTICS S 1FK7-CT 1.5kW 8.5Nm 2000rpm Servo Motor

The Siemens 1FK7062-2AC71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 1.5 kW, 8.5 Nm standstill torque (M0, 100K), and 2000 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.

Selection Notes

This 1FK7062-2AC71 winding is the lowest-speed option offered in the 1FK7062 frame, at 2000 rpm with a 2.83 Nm/A torque constant, so it needs only 2.6 A rated current for 8.5 Nm standstill torque. It ships without a holding brake, at 11.200 kgcm² moment of inertia and 37,000 Nm/rad shaft torsional stiffness. Faster windings are also available in the same frame at a lower torque constant; choose this one when minimizing drive current draw matters more than base speed. The 45.5 mH rotating field inductance and 3.59 Ω winding resistance both reflect the higher-turns winding needed to reach this low base speed, so size the drive's current-loop bandwidth accordingly.

Applications

Natural (fan-less) cooling and IP64 protection suit compact machine enclosures without forced airflow. The DRIVE-CLiQ interface connects directly to SINAMICS S120/S210 drive systems over a single feedback cable. At 8.5 Nm standstill torque and a 2000 rpm rated speed, it fits direct-drive or low-ratio-geared axes where torque, not speed, dominates the duty cycle.
