1FK7044-4CH71-1BH0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7044-4CH71-1BH0 is a premium synchronous motor built to deliver superior precision, efficiency, and power consistency in high-performance automation systems. This motor provides a rated power of 1.4 kW and a nominal torque of 4.5 Nm at 4500 rpm, making it ideal for dynamic industrial motion applications.

Designed with a naturally cooled structure and IP64 protection, it offers robust resistance against dust and splashes, ensuring long-term reliability even in demanding environments. The integrated 24-bit single-turn absolute encoder with DRIVE-CLiQ interface guarantees precise feedback for seamless control, while the rotatable power connector and holding brake enhance installation flexibility and operational safety.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ advanced generation of compact, permanent-magnet synchronous motors. These motors are engineered for exceptional versatility, capable of being tailored to a wide range of mechanical and automation applications. When paired with SINAMICS S120 or S220 drive systems, they form a fully integrated motion control solution with high responsiveness and accuracy. Their modular design allows customization through a selection of encoders, gearboxes, and mounting options, ensuring optimal adaptation to any machine configuration. The 1FK7 range is specifically optimized for operation without external cooling, using its housing to efficiently dissipate heat while maintaining consistent performance during intensive operation.

Design and Benefits

The 1FK7044-4CH71-1BH0 features a compact IMB 5 flange-mounted construction that facilitates easy integration into machinery layouts. Its high power density enables space-saving installation, making it suitable for confined mechanical systems. The SIMOTICS S-1FK7 series is available in multiple dynamic variants — Compact, High Dynamic, and High Inertia — each designed to deliver specific performance benefits. High Dynamic versions feature an extremely low rotor moment of inertia for rapid acceleration and precise control, while High Inertia models provide excellent stability under variable load conditions.

Typical applications include machine tools, robotic arms, packaging machinery, printing systems, and handling units, as well as wood, glass, and textile processing equipment. Each motor in this series demonstrates Siemens’ commitment to combining advanced control technology with mechanical durability, ensuring consistent, reliable, and energy-efficient motion performance.
