1FK7044-4CH71-1BH1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7044-4CH71-1BH1 is a premium synchronous servo motor designed for applications demanding exceptional accuracy, dynamic performance, and long-term reliability. Built for precision motion control, this model features a rated power of 1.4 kW and a torque of 4.5 Nm at a nominal speed of 4500 rpm. It operates with a 600V DC supply and is naturally cooled, offering a balance between compact design and high performance. The plain shaft with tolerance N and integrated holding brake ensure mechanical stability in demanding automation setups. A 24-bit single-turn absolute encoder with DRIVE-CLiQ interface (AS24DQI) provides high-resolution position feedback, ensuring efficient communication and control accuracy.

Overview

The SIMOTICS S-1FK7 series represents the latest generation of permanent-magnet synchronous motors from Siemens. Renowned for compact design and versatility, these motors are built for universal use in modern automation systems. The combination of various encoders, mechanical designs, and optional gearboxes makes the SIMOTICS S family adaptable to almost any application. When paired with the SINAMICS S120 or S220 drive systems, the 1FK7 motors form a highly efficient and flexible servo solution with advanced motion control capabilities. The integrated encoder technology ensures precise speed and position regulation, allowing smooth and responsive machine operation across diverse load conditions.

Design and Benefits

The 1FK7044-4CH71-1BH1 motor features a robust IP65 protection class housing and a rotatable power connector for flexible installation. Its high overload capacity allows consistent performance under variable operating loads. The SIMOTICS S-1FK7 range offers three distinctive variants — Compact, High Dynamic, and High Inertia — each engineered for specific operational demands. Users benefit from space-saving installation, fast response due to minimal rotor inertia, and reliable closed-loop control with minimal tuning effort. These characteristics make the SIMOTICS S-1FK7 series a trusted choice for machine tools, robotics, packaging equipment, and industrial automation processes requiring high torque density and efficiency.
