Siemens 1FK7062-2AH71-1QB0 SIMOTICS S 1FK7-CT 1.4kW 8.5Nm 4500rpm Brake Servo Motor

The Siemens 1FK7062-2AH71-1QB0 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 adds a holding brake and weighs 9.4 kg.

Technical Specifications

Selection Notes

This 1FK7062-2AH71 winding pairs the highest-speed 4500 rpm option in the 1FK7062 frame with a holding brake, for vertical or unbalanced high-speed axes that must hold position on power loss. 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 drive sizing. At 9.4 kg total weight, it carries the added mass of the brake assembly, consistent with the naturally cooled, IP64-rated construction shared across this 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 winding with holding brake fits vertical or unbalanced high-speed axes that must hold position on power loss.
