1FK7043-4CH71-1BH0 SIEMENS Exclusive High-Performance SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7-HD 1FK7043-4CH71-1BH0 is an advanced synchronous motor designed for modern industrial automation and precision machinery. With a rated power of 1.2 kW and a maximum speed of 4500 rpm, this motor combines compact dimensions, high efficiency, and reliable performance. Its naturally cooled design eliminates the need for additional cooling devices, dissipating heat directly through the motor surface. Built with a plain shaft (tolerance N) and a rotatable power connector, the motor is equipped with a 24-bit single-turn absolute encoder (AS24DQI) with a Drive CLIQ interface, providing precise speed and position feedback for demanding applications. The integrated holding brake and IP64 protection rating ensure safe and reliable operation in industrial environments.

Overview

The SIMOTICS S‑1FK7 series offers compact permanent-magnet synchronous motors suitable for a wide range of applications. These motors provide exceptional adaptability with various encoders, gearboxes, and optional features. By pairing with SINAMICS S120 or S220 drive systems, users gain a high-functionality combination suitable for advanced machinery. The motors’ robust design enables operation without external cooling, supporting a high overload capacity and reliable performance under continuous or variable loads.

Benefits & Applications

SIMOTICS S‑1FK7 motors deliver significant advantages across multiple industrial sectors. The compact design allows space-saving installations while offering high power density. High-dynamic models respond rapidly to control signals, ideal for precise motion control. High-inertia variants provide robust closed-loop control even under variable load conditions. Minimal commissioning effort is required, reducing downtime and setup complexity. These motors are suitable for machine tools, robotic and handling systems, wood, glass, ceramics, and stone processing, packaging, plastics, textile machines, printing, and auxiliary axes. The combination of high performance, flexibility, and precision makes the 1FK7043-4CH71-1BH0 an ideal solution for modern industrial automation.
