1FK7042-2AF71-1CG1-ZJ36 SIEMENS Exclusive SIMOTICS S-1FK7 Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor with model number 1FK7042-2AF71-1CG1-ZJ36 represents precision, efficiency, and durability for modern automation systems. This synchronous motor delivers a rated power of 0.82 kW and a torque of 3 Nm at 3000 r/min, offering consistent performance under continuous operation. Designed for natural cooling and high protection standards, the unit ensures long-term reliability even in demanding industrial environments. The integrated DRIVE-CLiQ encoder system allows precise feedback for speed and position control, providing exceptional motion accuracy.

Overview

The SIMOTICS S-1FK7 family is engineered for versatility and compactness, enabling smooth integration into a variety of automation applications. Thanks to its permanent-magnet synchronous design, the motor offers excellent dynamic response and energy efficiency. When paired with the SINAMICS S120 or S220 drive systems, it forms a high-performance motion control solution with advanced functionality. The system's modular design supports flexible adaptation through multiple encoder types, shaft configurations, and gearbox options, making it suitable for customized machinery layouts.

Design and Performance

This 1FK7042-2AF71-1CG1-ZJ36 variant features an ALPHA SP+ SP 100S-MF2 planetary gearbox with a two-stage ratio of i = 40, providing efficient torque transmission and precise motion control. Its plain shaft without holding brake and IP65 protection rating ensure smooth operation with minimal maintenance. The motor’s lightweight yet rugged construction allows space-saving installation while maintaining high torque density. An absolute encoder (AM24DQI, 24-bit + 12-bit multiturn) enables accurate feedback, making this model ideal for synchronized axes and servo-controlled motion.

Applications

The SIMOTICS S-1FK7 series serves a broad range of automation fields such as machine tools, robotics, packaging, textile processing, and material handling. It is equally well-suited for systems in wood, glass, ceramics, and stone working industries, as well as for high-precision printing and auxiliary drives. The motor’s high overload capability and efficient heat dissipation make it a trusted choice for both dynamic and high-inertia applications. Wherever reliability, precision, and compact performance are required, the 1FK7042-2AF71-1CG1-ZJ36 sets the benchmark for industrial motion excellence.
