1FK7042-2AF71-1UB0 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor with part number 1FK7042-2AF71-1UB0 is a precision-engineered synchronous servo motor designed for exceptional performance and durability in industrial automation. Delivering 0.82 kW nominal power and 3 Nm torque at 3000 rpm, it ensures accurate motion control with high reliability. The naturally cooled construction and IMB 5 (IM V1, IM V3) flange mounting allow flexible integration into a wide variety of machine designs. Equipped with a multi-pole resolver and DRIVE-CLiQ interface, this motor provides seamless connectivity and compatibility with SINAMICS drive systems. The addition of a holding brake and IP64 protection class makes it suitable for demanding environments.

Overview

The SIMOTICS S-1FK7 family represents a new standard in servo motor technology. These compact permanent-magnet synchronous motors combine high torque density with efficient energy consumption. Designed for universal use, they adapt to numerous applications requiring speed accuracy and dynamic response. When combined with the SINAMICS S120 or S220 drive systems, they form a high-performance servo solution that delivers precision, responsiveness, and operational reliability. The motors feature integrated encoder systems that can be tailored for various feedback requirements, ensuring smooth speed and position control.

Design and Benefits

The 1FK7042-2AF71-1UB0 motor uses a naturally cooled housing that efficiently dissipates heat through its surface, eliminating the need for external cooling. It features a rotatable power connector for simplified installation and a shaft with feather key tolerance N for robust mechanical coupling. The compact design saves valuable space while maintaining high torque output and operational stability.

Users benefit from simple commissioning, minimal maintenance, and long service life. The motor’s high overload capability ensures dependable operation even under variable load conditions. With versions optimized for Compact, High Dynamic, and High Inertia performance, this series meets the diverse requirements of modern industrial systems. Applications include machine tools, robotics, packaging, printing, and material-handling equipment — all areas where precision, speed, and reliability are essential.
