Siemens 1FK7083-5AF71-1AB0 is a permanent-magnet synchronous servo motor in the 1FK7 family for controlled axes in industrial machines. The exact version is specified with 10.5 Nm torque, 7.4 A current and a speed of 3,000 min⁻¹. An incremental encoder with 2,048 signal periods per revolution provides position and speed feedback for reproducible motion control. Siemens documentation describes the 1FK7 family as synchronous motors using rare-earth permanent magnets. The stator winding has temperature class F and includes a KTY-84 sensor for motor-temperature monitoring. The motor is self-cooled through its surface and has IP64 protection. Documented mounting arrangements are IM B5 and the vertical positions IM V1 and IM V3. The standard shaft end is smooth and has no keyway. Applications include machine tools, robotic and handling systems, packaging machines and auxiliary axes. Installation altitude is permitted up to 1,000 m without power derating, and vibration severity grade A supports mechanically smooth operation. For replacement, compare the complete order number, encoder, connector position, shaft form, flange and existing motor cables with the installed axis. Controller parameters, motor data and the machine's holding-brake concept must also match before installation. The combination of 10.5 Nm, 3,000 min⁻¹ and incremental feedback clearly identifies this version for an existing 1FK7 servo drive.
