1FK7042-2AK71-1RH1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7042-2AK71-1RH1 is a compact, high-precision synchronous motor engineered to deliver efficiency and stability across industrial automation applications. With a rated power of 0.94 kW and a torque of 3 Nm, this motor is optimized for 600 V DC operation and 6000 rpm nominal speed. Its naturally cooled, flange-mounted design (IM B5/IM V1/IM V3) and rotatable power connector allow flexible integration into mechanical assemblies, ensuring reliable operation and reduced maintenance requirements.

Equipped with an advanced AM20DQI Drive-CLiQ encoder providing 20-bit absolute and 12-bit multi-turn feedback, the motor guarantees precise speed and position control. The smooth shaft design with integrated holding brake and IP65 protection makes it ideal for environments demanding high performance and durability. Designed for continuous operation without external cooling, heat dissipation occurs efficiently through the motor’s surface, extending its service life while maintaining performance consistency.

Overview

The SIMOTICS S 1FK7 series represents the next generation of permanent-magnet synchronous motors. Compact dimensions, wide configuration options, and integrated encoder technology allow seamless adaptation to diverse industrial tasks. When paired with SINAMICS S120 or S220 drive systems, the motor forms a high-functionality motion solution delivering accuracy, responsiveness, and smooth operation under varying load conditions.

Design and Benefits

  • High power density enabling space-saving installation and lightweight construction
  • Low rotor moment of inertia for rapid acceleration and excellent dynamic response
  • Rugged closed-loop control behavior for variable load applications
  • Easy commissioning and minimal tuning effort in automation systems
  • Ideal for machine tools, robotics, packaging, plastics, textile, and printing machinery
