1FK7042-2AF71-1RG1-ZK23 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor represents a new generation of compact synchronous motors that deliver remarkable efficiency, smooth operation, and consistent reliability for industrial automation systems. With a nominal power of 0.82 kW and a rated speed of 3000 r/min, this model combines mechanical precision with long-term performance stability. Designed with a naturally cooled structure and a rugged IP65 protection class, it is engineered for durability even in demanding environments. The plain shaft with tolerance class N, integrated DRIVE-CLiQ interface, and 20 + 12-bit multiturn absolute encoder (AM20DQI) ensure high-accuracy feedback and responsive control.

The SIMOTICS S-1FK7 motor line is part of a modular family that easily integrates with the SINAMICS S120 or S220 drive systems, creating a scalable motion solution. Its high power density allows for compact installation without sacrificing torque output or system stability. The 1FK7042-2AF71-1RG1-ZK23 variant also includes a primer and anthracite paint finish (K23), offering superior surface protection against wear and corrosion.

Overview

The SIMOTICS S-1FK7 series combines permanent-magnet technology with advanced encoder options to meet the diverse requirements of modern automation. Available in multiple configurations — Compact, High Dynamic, and High Inertia — these motors can be tailored precisely to machine design needs. They offer space-saving installation, high overload capacity, and fast acceleration response, making them an ideal choice for dynamic and continuous-duty applications.

Applications and Benefits

Typical uses include machine tools, robotics, packaging machinery, glass and ceramic processing, and auxiliary axes in automated systems. The low rotor moment of inertia allows for exceptional motion control, while the closed-loop regulation ensures stable performance even under variable loads. Easy commissioning, minimal maintenance, and compatibility with existing automation systems make the SIMOTICS S-1FK7 one of the most reliable servo motor solutions available.
