1FK7042-2AF71-1PB2 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 with part number 1FK7042-2AF71-1PB2 is a premium-grade synchronous motor designed to deliver precise performance, long-term reliability, and superior efficiency in modern automation systems. Engineered with a naturally cooled compact structure, it offers a rated power of 0.82 kW, rated torque of 3 Nm, and a nominal speed of 3000 rpm. The unit is built for durability with an IP65-rated body and IP67 front flange, ensuring robust protection even in demanding industrial environments.

Equipped with a rotatable power connector and a 2-pole resolver featuring DRIVE-CLiQ interface, this motor provides seamless communication with SIEMENS drive systems such as SINAMICS S120 or S220. The integrated holding brake and shaft with feather key guarantee safe torque transmission and stable positioning during operations. This makes the motor highly adaptable across various configurations and applications requiring high torque accuracy and dynamic control.

Overview

The SIMOTICS S-1FK7 family is designed for flexibility and performance. These permanent-magnet synchronous motors combine compact size with exceptional torque density, enabling efficient use of space in machinery layouts. The heat generated during operation is effectively dissipated through the motor surface, eliminating the need for additional cooling components. As a result, system complexity and maintenance requirements are minimized while maintaining consistent performance.

Each motor variant within the 1FK7 range is optimized for specific motion profiles. The Compact models offer universal application with high power density; the High Dynamic versions deliver rapid acceleration for motion-intensive tasks; and the High Inertia types ensure smooth, stable operation where load variability is significant. With precise encoder systems and optional gear configurations, this product line meets the evolving needs of modern machinery.

Applications

Typical applications include machine tools, robotic systems, packaging and printing equipment, as well as machinery for wood, glass, ceramics, plastics, and textiles. The combination of power, efficiency, and adaptability makes the 1FK7042-2AF71-1PB2 SIEMENS SIMOTICS S-1FK7 an ideal choice for advanced automation environments requiring continuous performance and minimal downtime.
