1FK7044-4CF71-1QA1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7044-4CF71-1QA1 is a high-performance permanent-magnet synchronous motor designed for precision and efficiency in modern automation systems. With a rated power of 1.2 kW and a torque of 4.5 Nm, this advanced motor provides reliable speed and position control in demanding environments.

Operating at a nominal speed of 3000 rpm and powered by a 600 V DC link voltage, it offers consistent performance and smooth motion control. The unit features a naturally cooled design, a robust IP65 protection rating, and a rotatable power connector for flexible installation. The integrated absolute single-turn encoder with DRIVE-CLiQ interface ensures precise feedback and compatibility with SINAMICS drive systems. This configuration makes it an exceptional choice for users seeking precision, durability, and seamless integration in motion control applications.

Overview

The SIMOTICS S-1FK7 motor series from Siemens represents a new generation of compact and efficient synchronous motors. Each motor is engineered with a permanent-magnet rotor that delivers outstanding dynamic response and high torque density, allowing for shorter cycle times and smoother operations. These motors can be combined with SINAMICS S120 or S220 drive systems to create a highly functional, energy-efficient motion solution suitable for a wide range of applications. With integrated encoders for accurate position and speed detection, the system provides excellent control precision while minimizing maintenance requirements. The motors are designed for surface cooling, ensuring reliable heat dissipation and prolonged operational life even in continuous-duty environments.

Design and Application

The 1FK7044-4CF71-1QA1 features a rugged frame with flange mounting (IMB 5, IM V1, IM V3) and a shaft with fitted key, tolerance N, without holding brake. Its rotatable power connector simplifies cable management in tight installations, while its naturally cooled body supports low-noise and vibration-free performance. These motors are ideal for precision applications such as machine tools, robotics, packaging systems, and textile machinery. Additionally, they are well-suited for wood, glass, ceramics, and printing equipment where dynamic performance and positioning accuracy are essential. Designed for high dynamic response and superior stability, this model offers a dependable foundation for advanced industrial automation systems.
