1FK7042-2AF21-1RG0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AF21-1RG0 represents the next generation of precision servo motors engineered for reliability and performance in industrial automation. This synchronous motor delivers a rated power of 0.82 kW with a torque of 3 Nm at a nominal speed of 3000 rpm. Operating at a DC voltage of 300 V, the unit’s compact, naturally cooled design ensures consistent efficiency even under demanding conditions. Built with an IP64 protection rating and a smooth, tolerance-class N shaft, it is ideal for clean and controlled industrial environments.

Overview

The SIMOTICS S-1FK7 motor series features compact, permanent-magnet synchronous motors optimized for high-precision motion control. Its broad range of variants, combined with compatible encoders and gearboxes, allows effortless adaptation to a wide spectrum of automation systems. When paired with the SINAMICS S120 or S220 drive systems, it forms a powerful, flexible drive solution offering exceptional speed and position accuracy. The integrated encoder AM20DQI with 20-bit absolute and 12-bit multi-turn resolution provides precise digital feedback through the DRIVE-CLiQ interface, ensuring smooth control and dependable performance.

Design and Performance

The 1FK7042-2AF21-1RG0 motor is engineered for natural cooling, allowing heat dissipation directly through the surface without additional fans or air systems. This results in reduced maintenance requirements and increased longevity. Its high overload capacity guarantees consistent torque even in high-demand operations, while the rotatable power connector simplifies installation in space-restricted areas. Designed for IMB5 (IM V1, IM V3) flange configurations, it offers versatile mounting options to suit various machine layouts.

This model is particularly suitable for machine tools, packaging and textile lines, robotics, and other automated applications requiring stable torque, fast response, and reliable feedback. With outstanding mechanical design, durable construction, and advanced encoder integration, the SIMOTICS S 1FK7 series ensures continuous precision and long-term productivity.
