1FK7043-4CH71-1QG1 SIEMENS Exclusive High-Dynamic Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CH71-1QG1 is a compact and high-performance synchronous motor designed to deliver precise motion control and reliability across a wide range of industrial applications. Built with a power rating of 1.2 kW and rated torque of 3.5 Nm, this motor ensures efficient power transmission and consistent operation under demanding conditions. Its naturally cooled frame (IMB5 / IMV1 / IMV3) and IP65 protection enable stable performance even in harsh environments.

The integrated AS20DQI absolute encoder provides accurate position feedback through a DRIVE-CLiQ interface, ensuring exceptional synchronization with SIEMENS SINAMICS drive systems. Engineered for long-term reliability and low maintenance, this exclusive SIMOTICS S model represents the perfect balance between precision, power, and durability.

Overview

SIMOTICS S-1FK7 motors are premium permanent-magnet synchronous motors that combine compact design with superior performance. The series offers a wide range of mechanical and electrical variants, allowing flexible adaptation to different automation setups. When combined with SINAMICS S120 or S220 drive systems, the motor forms an efficient, highly dynamic, and fully digital drive package suitable for advanced industrial processes.

Designed for surface cooling without external fans, the motor ensures optimized heat dissipation through its metal housing, supporting extended service life and reduced operational costs. With high overload capacity and seamless encoder integration, the 1FK7 series delivers outstanding speed and torque control for precision-driven machinery.

Design and Benefits

The SIMOTICS S 1FK7043-4CH71-1QG1 is available in various configurations tailored for specific performance needs. The Compact variant ensures space-saving installation, the High Dynamic version offers exceptional acceleration due to its low rotor inertia, and the High Inertia type delivers smooth, stable motion for applications with variable loads.

These design options make it suitable for applications such as machine tools, robotics, packaging, printing, and material handling. Each motor features a plain shaft with N-class tolerance, ensuring precision alignment during assembly. Its rotatable power connector allows flexible installation, while the absence of a holding brake simplifies integration into systems requiring continuous rotation.
