1FK7043-4CH71-1BG2 SIEMENS Exclusive High-Performance Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7-HD 1FK7043-4CH71-1BG2 is a precision-engineered permanent-magnet synchronous motor designed for demanding industrial applications. With a nominal power of 1.2 kW and operating voltage of 600 V, this motor delivers reliable performance across a wide range of mechanical and automation systems. Featuring a rotatable power connector and a single-turn 24-bit absolute encoder with Drive CLIQ interface, the 1FK7043-4CH71-1BG2 ensures precise position and speed control, making it ideal for high-accuracy machinery.

Overview

The SIMOTICS S‑1FK7 motors are compact, high-performance motors optimized for seamless integration with SINAMICS S120 and S220 drive systems. Their versatile design allows for optional gearboxes and encoders, making these motors suitable for a wide variety of industrial applications. Naturally cooled with no external cooling required, the motors dissipate heat efficiently through the surface while maintaining high overload capacity. This combination of compact design and robust performance ensures reliable operation even under continuous high-load conditions.

Benefits

The compact configuration of the SIMOTICS S‑1FK7 motors saves space while providing high power density for universal applications. High dynamic variants offer extremely responsive operation due to low rotor inertia, whereas high inertia versions provide stable closed-loop control under varying or high load conditions. These features minimize setup and commissioning time, reducing downtime during system integration or maintenance.

Applications

These motors are ideal for a wide spectrum of machinery, including machine tools, robotic systems, handling equipment, packaging machines, plastics, textile and printing machines, as well as auxiliary axes in complex automation environments. The robust IP65/67 protection ensures reliable operation in harsh industrial conditions, while the plain shaft design with tolerance N allows for flexible mechanical integration.
