1FK7044-4CH71-1RA1 SIEMENS Exclusive High-Performance SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7044-4CH71-1RA1 is a compact, high-performance synchronous motor designed for demanding industrial applications where reliability, precision, and efficiency are paramount. With a nominal power of 1.4 kW and a rated speed of 4500 rpm, this naturally cooled motor operates seamlessly without external cooling devices. Its robust construction, including a rotatable power connector and IP65 protection, ensures durability and safe operation in harsh industrial environments.

Overview

Part of the SIMOTICS S‑1FK7 series, these compact permanent-magnet synchronous motors offer high flexibility through a wide range of options, gearboxes, and encoder configurations. Designed for integration with the SINAMICS S120/S220 drive systems, the 1FK7044-4CH71-1RA1 ensures precise speed and position control, making it ideal for machine tools, robots, packaging machines, and handling systems. The built-in 20-bit absolute encoder with 12-bit multiturn functionality and DRIVE-CLiQ interface guarantees accurate feedback and efficient system performance.

Benefits

These motors provide space-saving installation due to high power density, making them suitable for applications with restricted space. They offer extremely high dynamic response with minimal rotor inertia, ensuring fast acceleration and precise motion control. For applications with high or variable load moments of inertia, the robust closed-loop control of the motor provides consistent performance with minimal optimization or commissioning overhead. The motor’s surface-dissipated heat allows continuous operation even under demanding conditions, reducing maintenance requirements.

Applications

• Machine tools and auxiliary axes
• Robots and automated handling systems
• Wood, glass, ceramics, and stone processing machines
• Packaging, plastics, and textile machinery
• Printing machines
