1FK7042-2AF71-1RG1-ZJ12 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 1FK7042-2AF71-1RG1-ZJ12 is a high-precision synchronous motor engineered for superior reliability and performance in demanding industrial environments. This advanced motor delivers a rated power of 0.82 kW with a torque of 3 Nm (100 K) and a rated speed of 3000 rpm, ensuring smooth and stable operation in both continuous and dynamic applications. Its naturally cooled design (IMB 5 / IM V1 / IM V3 mounting types) and IP65 protection make it perfectly suited for modern automation systems where efficiency, compactness, and accuracy are essential.

Equipped with an absolute encoder (20-bit + 12-bit multiturn) and DRIVE-CLiQ interface (encoder AM20DQI), the SIMOTICS S-1FK7 provides precise feedback for position and speed control. The plain shaft with tolerance N and the integrated ALPHA SP+ SP 060S-MF2 planetary gearing (2 stages, ratio 16) ensure smooth mechanical power transmission with minimal backlash. Built for maximum compatibility, this motor integrates seamlessly with SINAMICS S120 and S220 drive systems, forming a powerful automation solution for high-performance motion control.

Overview

The SIMOTICS S-1FK7 motor family represents the next generation of compact permanent-magnet synchronous motors from SIEMENS. Their versatile configuration options — including multiple shaft types, gearbox combinations, and encoder systems — allow engineers to tailor each motor to specific industrial requirements. The result is a flexible and future-proof solution that meets the increasing performance demands of today’s machines. By combining these motors with the SINAMICS drive platform, users achieve precise motion control, fast acceleration, and efficient energy use across a broad range of applications.

Benefits

The SIMOTICS S-1FK7 Compact motors offer space-saving installation and excellent power density for universal applications across multiple industries. The High Dynamic versions deliver rapid response thanks to low rotor inertia, while the High Inertia models ensure stable control under varying loads. Together, these features enable high-precision operation, reduced commissioning effort, and increased machine availability. Each motor is built to maintain high efficiency and durability even in continuous operation, making it a preferred choice for automation professionals.
