Siemens 1FK7062-2AH71-1QA0 SIMOTICS S 1FK7-CT 1.4kW 8.5Nm 4500rpm Servo Motor

The Siemens 1FK7062-2AH71-1QA0 is a SIMOTICS S 1FK7-CT synchronous servo motor rated 1.4 kW, 8.5 Nm standstill torque (M0, 100K), and 4500 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 and weighs 9.101 kg.

Technical Specifications

Selection Notes

This 1FK7062-2AH71 winding is the highest-speed option offered in the 1FK7062 frame at 4500 rpm, and it ships without a holding brake, suiting horizontal or gravity-balanced high-speed axes. Detailed electromechanical constants — torque constant, moment of inertia, winding resistance — are not present in the verified PDF dataset for this order number; confirm them against the full datasheet before sizing the drive. At 8.5 Nm standstill torque and 4500 rpm, this winding targets applications that need base speed over holding torque, within a naturally cooled, IP64-rated frame.

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. The 4500 rpm rated speed suits belt-driven or geared axes that need higher throughput at 8.5 Nm standstill torque, without a holding brake to release before motion.
