1FK7042-2AF71-1QA1 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 synchronous motor, part number 1FK7042-2AF71-1QA1, is an advanced compact drive solution engineered for precision motion and durability. Delivering a rated power of 0.82 kW with 3 Nm torque and 3000 rpm speed, this motor provides exceptional performance for high-accuracy industrial applications. Designed with a naturally cooled enclosure and IP65 protection, it ensures reliable operation even in demanding environments where dust and moisture protection are essential.

This version of the SIMOTICS S-1FK7 features a rotatable power connector and a single-turn 20-bit absolute encoder with DRIVE-CLiQ interface (type AS20DQI), ensuring precise feedback and easy integration into modern automation systems. The shaft with feather key guarantees accurate mechanical coupling, and its maintenance-free design enhances long-term operational stability. The combination of compact size, mechanical robustness, and intelligent connectivity makes this motor a preferred choice for applications requiring exact motion control.

Overview

The SIMOTICS S-1FK7 motor family comprises compact permanent-magnet synchronous motors offering a broad selection of power ratings and configurations. They are ideal for use with the SINAMICS S120 and S220 drive systems, creating a high-performance mechatronic unit for automation tasks. Integrated encoder systems enable precise speed and position control, meeting the ever-growing requirements of modern machine designs. Compact construction and high power density allow for installation in space-restricted areas without sacrificing efficiency or responsiveness.

Design and Applications

The motor is engineered for operation without external cooling, with heat dissipation through the housing surface to maintain consistent temperature performance. Its high overload capacity and dynamic response make it suitable for machine tools, robots, packaging equipment, printing systems, and textile machines. Different variants within the S-1FK7 series include Compact, High Dynamic, and High Inertia types — each optimized for specific load requirements. This versatility ensures smooth motion profiles, low vibration, and reduced commissioning effort for varied industrial applications.
