1FK7042-2AF71-1RA2 SIEMENS Exclusive SIMOTICS S-1FK7 Compact Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor (1FK7042-2AF71-1RA2) is a compact and high-performance servo motor engineered for precision and reliability in modern automation environments. Designed with an impressive power rating of 0.82 kW and a rated speed of 3000 rpm, this naturally cooled motor combines energy efficiency with robust construction. Its integrated DRIVE-CLiQ absolute encoder ensures precise position feedback and seamless communication within the SINAMICS S120 / S220 drive system, providing users with maximum control accuracy and stability in dynamic applications.

Built to deliver consistent torque of 3 Nm (100 K), the motor utilizes advanced permanent-magnet technology for superior responsiveness. The rotatable power connector, IP65/IP67 protection rating, and shaft with feather-key design guarantee easy installation and durable operation even under demanding industrial conditions. As part of the SIMOTICS S family, it meets the highest standards of Siemens engineering and is ideal for machine tools, robotics, packaging, and handling systems where compactness, reliability, and precision are crucial.

Overview

The SIMOTICS S-1FK7 series represents Siemens’ latest generation of permanent-magnet synchronous motors, offering exceptional flexibility through a wide selection of frame sizes, feedback systems, and mounting options. The combination of mechanical robustness and high energy efficiency allows integration into compact machines without compromising performance. Each motor can be perfectly matched with Siemens SINAMICS drive systems to create a synchronized motion platform that enhances overall productivity and control precision.

These motors are optimized for natural cooling, allowing heat to dissipate efficiently through the outer surface. The design ensures high overload capacity, stable operation, and long service life, making it a dependable choice for automation tasks that require both endurance and responsiveness.

Benefits and Applications

The SIMOTICS S-1FK7 Compact motors save space with their high power density and are suitable for universal use across diverse industries. High Dynamic versions offer excellent acceleration thanks to low rotor inertia, while High Inertia types provide stable closed-loop performance for applications with variable loads. They minimize commissioning time and simplify parameter optimization.

Typical uses include machine tools, robotic arms, material-handling systems, and specialized equipment in wood, glass, ceramics, and packaging industries. The motor’s consistent accuracy, low noise, and long-term reliability make it a preferred solution for automated production lines and precision manufacturing.
