1FK7042-2AF71-1RB0 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS 1FK7042-2AF71-1RB0 SIMOTICS S-1FK7 motor is a high-efficiency synchronous servo motor engineered for precision motion and reliability in industrial automation. Delivering a rated power of 0.82 kW at 600 V DC and a rated torque of 3 Nm, it is designed for 3000 rpm operation with natural cooling and robust IP64 protection. Its compact structure and rotatable power connector enable flexible installation across diverse applications where space optimization and consistent performance are essential. The integrated absolute encoder (AM20DQI 20 bit + 12 bit multiturn DRIVE-CLiQ) ensures accurate feedback and seamless integration with SINAMICS drive systems.

Overview

The SIMOTICS S-1FK7 series represents the next generation of permanent-magnet synchronous motors built for accuracy, endurance, and high dynamic response. These motors can be paired effortlessly with SINAMICS S120 and S220 drives to form a complete servo system delivering superior torque control and motion stability. Each motor is optimized for performance without external cooling; heat is dissipated through its rugged surface, maintaining efficiency and minimizing maintenance needs. Thanks to the wide selection of variants, encoders, and gear options, the S-1FK7 range is adaptable to virtually any modern automation task.

Design and Benefits

The 1FK7042-2AF71-1RB0 model exemplifies space-saving design and high power density, supporting both IMB 5 (IM V1, IM V3) mounting configurations. It incorporates a feather-key shaft, high-precision bearings, and an integrated holding brake for safety and operational stability. The naturally cooled construction allows quiet and efficient operation, ideal for compact machinery. Benefits include rapid dynamic response, superior positioning accuracy, and robust closed-loop control even under fluctuating loads. This flexibility makes the S-1FK7 motors indispensable for cutting-edge machine generations requiring reliability and consistent torque output.

Applications

Typical uses include machine tools, packaging systems, robotics, handling units, and specialized processing equipment for wood, glass, ceramics, textiles, and printing. Its high-inertia variants ensure stable performance under varying loads, while the low-inertia versions deliver lightning-fast response in precision motion applications. Built on proven SIEMENS engineering excellence, the S-1FK7 series guarantees outstanding efficiency and a long service life, contributing to reduced downtime and overall system optimization.
