1FK7042-2AC71-1FG1-ZJ02 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AC71-1FG1-ZJ02 is a premium-grade synchronous servo motor built for modern automation environments that require precision, reliability, and energy efficiency. Delivering 0.59 kW rated power with a torque of 3 Nm at 2000 rpm, this naturally cooled model is ideal for consistent, high-accuracy performance across multiple industrial applications. Its robust mechanical design ensures long service life, while the IP65 protection rating guarantees excellent durability in challenging production conditions. This configuration includes an AM22DQ absolute encoder (22-bit + 12-bit multiturn) featuring DRIVE-CLiQ interface for seamless connectivity and optimized feedback precision.

With its rotatable power connector and plain shaft with tolerance N, the motor is engineered for straightforward integration and adaptability. The addition of the ALPHA SP+ SP 075S-MF1 planetary gear unit (ZJ02) with a single-stage ratio of i = 4 enhances torque output and efficiency while maintaining compact dimensions. The combined system ensures smooth torque transmission, reduced vibration, and optimal control response in high-precision motion tasks.

Overview

SIMOTICS S-1FK7 motors are compact permanent-magnet synchronous drives designed for dynamic and precise motion control. Thanks to a modular range of encoders, mechanical interfaces, and gear options, they can be configured for a wide variety of mechanical requirements. When paired with SINAMICS S120 or S220 drive systems, they deliver excellent system synergy, ensuring high-speed, smooth operation, and advanced diagnostic capabilities. The integrated encoder technology supports precise position and velocity control, making it suitable for automated systems where motion accuracy and repeatability are critical. Operating without external cooling, the motor efficiently dissipates heat through its surface, enabling continuous duty cycles without performance degradation.

Applications and Benefits

The 1FK7042-2AC71-1FG1-ZJ02 motor excels in machine tools, robotic arms, handling systems, and other precision-driven industrial applications. It is also well-suited for wood, glass, ceramic, packaging, printing, and textile processing machinery. Benefits include compact installation thanks to high power density, flexible configuration for multiple machine concepts, and outstanding servo performance with minimal commissioning effort. Users can expect robust closed-loop behavior, rapid dynamic response, and dependable performance over extended operational periods—making this motor an excellent investment for advanced manufacturing systems.
