1FK7042-2AK71-1RB0-ZR72 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1RB0-ZR72 represents the next generation of compact, high-precision synchronous motors designed for industrial applications that demand performance, durability, and smooth operation. Delivering a rated power of 0.94 kW and a torque of 3 Nm at 6000 rpm, this motor ensures stable and efficient motion in automation systems. It operates at a DC link voltage of 600 V and features a naturally cooled IMB 5 design suitable for versatile mounting orientations (IM V1, IM V3). The rotatable power connector and high-accuracy encoder options make integration straightforward across a variety of setups.

This advanced motor includes an absolute encoder AM20DQI with 20-bit + 12-bit multi-turn precision and a Drive-CLiQ interface, providing reliable feedback for superior control accuracy. The robust shaft with a feather key, N-class tolerance, and integrated holding brake ensures dependable mechanical connection and secure stopping power. Rated with IP64 protection, it resists dust and splashing water, making it ideal for demanding environments. The ZR72 variant integrates an incremental encoder JH for additional feedback versatility, allowing compatibility with various motion-control configurations.

Overview

SIMOTICS S-1FK7 motors are permanent-magnet synchronous drives that combine compact design with high power density. Their extensive range of encoder and gearbox options allows flexible adaptation to machine-specific needs. When paired with SINAMICS S120 or S220 drive systems, these motors deliver precise motion, rapid response, and efficient energy conversion, ensuring outstanding performance in dynamic industrial processes.

Design and Benefits

• Compact construction for space-saving installation and easy integration
• High overload capacity for short-term torque peaks without thermal issues
• Excellent torque control and smooth rotation for precision applications
• Available in Compact, High Dynamic, and High Inertia variants for different mechanical loads
• Low rotor moment of inertia for exceptional dynamic response
• Minimal commissioning effort due to stable closed-loop control characteristics

These motors are widely applied in machine tools, robotics, packaging equipment, and textile or printing systems, where consistent performance and high reliability are crucial. Designed to operate without external cooling, the SIMOTICS S 1FK7042-2AK71-1RB0-ZR72 efficiently dissipates heat through its surface, maintaining temperature stability and extending service life.
