1FK7044-4CH71-1BG2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7044-4CH71-1BG2 SIMOTICS S Synchronous Motor is a premium high-performance motor engineered for precision-driven automation and motion control systems. With a rated power of 1.4 kW and a rated torque of 4.5 Nm at 4500 rpm, this naturally cooled motor ensures efficient, reliable operation in continuous industrial use. The model is built with a rotatable power connector and an absolute encoder singletur​n 24-bit with DRIVE-CLiQ interface, providing exact positioning and communication within complex motion applications. Its plain shaft design, IP65 motor protection (IP67 at the flange), and high structural integrity ensure long service life and stability even under demanding mechanical conditions.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ advanced line of compact permanent-magnet synchronous motors, purpose-built for precision motion control. These motors can be easily combined with the SINAMICS S120 or S220 drive systems to create a highly dynamic and efficient servo drive solution. The integrated encoder technology offers superior speed and position control, while the natural cooling design efficiently manages heat dissipation without external fans. With a high overload capacity and optimized mechanical configuration, the SIMOTICS S-1FK7 line ensures both performance and reliability across diverse automation environments.

Design and Benefits

The 1FK7044-4CH71-1BG2 features a rugged frame (IMB 5, IM V1, IM V3) and a naturally cooled housing that ensures stable thermal management. The compact build provides space-saving installation and exceptional power density, making it ideal for high-performance applications. The High Dynamic variant offers low rotor inertia for rapid acceleration and smooth control, while the High Inertia version provides robust closed-loop stability in systems with varying load conditions. This adaptability reduces commissioning time and enables consistent performance under fluctuating torque demands.

Applications

The SIMOTICS S-1FK7 motor range, including this model, is suitable for numerous applications such as machine tools, robotics, packaging systems, textile and printing machinery, and precision handling equipment. Industries working with wood, ceramics, glass, or stone also benefit from its exceptional control response and durability. Whether for auxiliary axes or high-precision positioning systems, this motor delivers uncompromised performance and efficiency.
