1FK7042-2AF71-1RH0-ZN05 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AF71-1RH0-ZN05 is a compact, high-precision synchronous motor engineered for modern automation and motion control systems. Delivering a rated power of 0.82 kW at a voltage of 600 V DC and a torque of 3 Nm (100 K), this unit provides exceptional efficiency and smooth performance for dynamic industrial environments. The naturally cooled design with IMB 5 (IM V1, IM V3) construction ensures reliable thermal management, while its absolute multi-turn 20-bit encoder (AM20DQI) delivers accurate feedback for precise speed and position control. Designed with a plain shaft and an integrated holding brake, this motor offers stable and secure operation even under demanding workloads.

Overview

The SIMOTICS S-1FK7 series from SIEMENS represents a new generation of compact permanent-magnet synchronous motors designed for universal applications. Through a wide selection of frame sizes, torque ratings, and encoder systems, these motors can be configured for a diverse range of machine automation tasks. When combined with the SINAMICS S120 or S220 drive system, they create a robust and highly flexible motion solution. Built for operation without external cooling, the heat dissipation through the motor’s surface supports continuous duty cycles and extends service life. Its high overload capacity and compact size make it ideal for installations where efficiency and precision are critical.

Benefits

The SIMOTICS S-1FK7 Compact motor provides space-saving integration and exceptional power density, making it suitable for a broad range of automation and production equipment. Users benefit from a consistent performance profile, adaptable torque characteristics, and reliable control accuracy. The High Dynamic versions deliver ultra-responsive acceleration, while the High Inertia variants offer stable closed-loop control with minimal tuning effort. Overall, these features allow engineers to meet strict operational demands with reduced commissioning time and enhanced productivity.

Applications

This synchronous motor is widely used in machine tools, robotics, material-handling systems, packaging machinery, textile and printing equipment, and process automation. It ensures smooth motion, energy efficiency, and durability even under fluctuating load conditions. The 1FK7042-2AF71-1RH0-ZN05 variant features the ZN05 shaft compatibility, ensuring seamless mechanical integration with 1FT504X motor dimensions, providing engineers with flexible replacement and upgrade options.
