The SIEMENS SIMOTICS S-1FK7 synchronous motor 1FK7042-2AF71-1RH1-ZJ15 is an advanced servo drive solution engineered for precision, reliability, and long-term operational stability in industrial environments. With a nominal power of 0.82 kW and a rated torque of 3 Nm at 3000 r/min, this naturally cooled, compact design offers excellent energy efficiency and dynamic performance. Its absolute multiturn encoder with DRIVE-CLiQ interface enables highly accurate position feedback, ensuring perfect synchronization and control for demanding automation applications.

Overview

The SIMOTICS S-1FK7 series represents SIEMENS’ state-of-the-art permanent-magnet synchronous motors designed for versatile machine-building requirements. These motors combine compact construction with exceptional performance density, allowing machine builders to achieve greater functionality in a smaller footprint. When paired with the SINAMICS S120 or S220 drive system, they deliver smooth torque, efficient energy utilization, and outstanding reliability even under continuous operation. The integrated encoder options allow precise speed and position control tailored to any automation scenario.

Design and Benefits

The 1FK7042-2AF71-1RH1-ZJ15 motor features a robust IP65 housing for complete protection against dust and low-pressure water jets, making it ideal for industrial settings. The plain shaft with feather key ensures a secure mechanical connection, while the integrated holding brake improves safety during machine downtime. The unit supports a rotatable power connector, simplifying installation in restricted cabinet spaces. Its natural cooling system minimizes maintenance needs while providing consistent thermal performance.

Key advantages include compact design for space-saving integration, wide torque spectrum, and compatibility with planetary gearing ALPHA SP+ 100S-MF2 (two-stage I=28). This combination enables high-precision motion with low vibration, making it perfect for machine tools, packaging equipment, robotic systems, and material-processing machinery. The SIMOTICS S-1FK7 Compact, High Dynamic, and High Inertia variants offer flexibility for diverse loads, from rapid acceleration tasks to stable control of heavy axes.

With its excellent overload capability and advanced digital encoder, the 1FK7042-2AF71-1RH1-ZJ15 motor ensures smooth performance, minimal commissioning effort, and maximum uptime—an optimal solution for modern automation systems seeking reliability and energy efficiency.
