1FK7042-2AF71-1RH1-ZX52 SIEMENS Exclusive SIMOTICS S-1FK7 Compact Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 motor with part number 1FK7042-2AF71-1RH1-ZX52 is a compact, high-performance synchronous motor engineered for precision, efficiency, and long-term reliability in modern automation systems. Delivering a rated power of 0.82 kW at 3000 rpm and torque of 3 Nm (100 K), this naturally cooled servo motor ensures stable operation even under demanding load cycles. The design follows the IMB 5 (IM V1, IM V3) construction type, offering flexible installation for a variety of machine configurations. Its integrated absolute encoder AM20DQI with 20-bit + 12-bit multiturn resolution and DRIVE-CLiQ interface provides superior position accuracy and seamless connectivity with SINAMICS S120 or S220 drive systems.

Overview

The SIMOTICS S-1FK7 series represents the next generation of permanent-magnet synchronous motors by SIEMENS, designed for high power density within a minimal footprint. The S-1FK7 motors are available in multiple torque and speed configurations, allowing machine builders to tailor their systems precisely to the required application. The combination of lightweight construction and optimized magnetic design ensures minimal vibration, low noise levels, and extended mechanical lifespan.

Each motor is designed for operation without external cooling — heat dissipation occurs directly through the housing surface, resulting in maintenance-free, energy-efficient performance. The RAL 3000 blazing red paint finish (X52 variant) not only provides corrosion resistance but also offers a distinct industrial appearance.

Benefits

• Extremely compact footprint for space-saving machine integration
• High power-to-size ratio for optimized system efficiency
• Seamless compatibility with SINAMICS S120 and S220 drive systems
• Enhanced control precision with integrated DRIVE-CLiQ encoder
• Wide range of configurations covering compact, high-dynamic, and high-inertia versions
• Reliable thermal performance through natural cooling design

Applications

Typical applications include CNC machine tools, robotic arms, packaging lines, textile machinery, and other high-precision automation equipment. The SIMOTICS S-1FK7 motors provide stable operation across variable loads and support complex motion profiles in robotics, handling, and industrial production systems.
