1FK7044-4CH71-1RB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7044-4CH71-1RB2 SIMOTICS S Synchronous Motor represents a new standard in precision motion control for modern industrial systems. Designed for high-performance applications, this motor delivers 1.4 kW of rated power at 600 V DC and provides a torque of 4.5 Nm with a rated speed of 4500 rpm. Its naturally cooled design ensures efficient heat dissipation through the motor surface, minimizing maintenance requirements and maximizing reliability. The integrated absolute encoder (AM20DQI) with a 20-bit + 12-bit multiturn resolution and DRIVE-CLiQ interface guarantees exceptional positioning accuracy and feedback performance. With a fitted key shaft, N-tolerance, and holding brake, this compact drive solution is ideal for automation environments requiring dynamic, precise, and continuous motion control.

Overview

The SIMOTICS S-1FK7 series motors are permanent-magnet synchronous motors engineered to meet the growing needs of state-of-the-art machine generations. This series offers flexibility through an extensive range of motor variants, encoder options, and mechanical configurations, ensuring perfect adaptation to a wide range of industrial uses. When paired with the SINAMICS S120 or S220 drive system, the motor provides a complete motion solution with exceptional efficiency and precision control. These motors are designed for operation without external cooling, offering high overload capacity and long service life even under continuous-duty conditions.

Benefits

• Compact design with high power density for space-saving installation.
• High dynamic response due to a low rotor moment of inertia.
• Reliable closed-loop control for stable operation under varying load conditions.
• Wide selection of models, encoders, and mounting configurations for diverse needs.
• Simple integration with existing Siemens automation and drive platforms.

Applications

The 1FK7044-4CH71-1RB2 motor is widely used in machine tools, robotics and handling systems, as well as in packaging, textile, and printing machinery. It also supports applications in wood, glass, ceramics, and stone processing industries, where precision, responsiveness, and durability are critical for continuous production.
