1FK7044-4CF71-1QB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7044-4CF71-1QB2 is part of the renowned SIMOTICS S-1FK7 series, known for its high precision, durability, and superior performance in industrial automation. This synchronous motor delivers a nominal power output of 1.2 kW and a torque of 4.5 Nm (100K), operating at a speed of 3000 rpm with a rated voltage of 600V DC.

Designed for natural cooling and engineered with a rugged IMB 5 (IM V1, IM V3) flange mounting, this motor offers reliable performance in demanding machine environments. The rotatable power connector and integrated AS20DQI absolute encoder with Drive-CLiQ interface ensure precise control and easy integration with SIEMENS SINAMICS drive systems. The motor also includes a fitted key shaft with tolerance N and a holding brake, providing secure, stable operation in dynamic applications.

Overview

The SIMOTICS S-1FK7 series represents a new generation of compact, permanent-magnet synchronous motors developed to meet the evolving requirements of modern industrial machinery. These motors can be configured with various encoders, gear units, and mechanical options, making them suitable for a wide range of automation needs.

When paired with SINAMICS S120 or S220 drive systems, they deliver outstanding performance, responsiveness, and control precision. The integrated encoder system enables exact position and speed feedback, which enhances the overall productivity and efficiency of the automation line. Built with robust materials and IP65/IP67 protection, the motor resists dust and moisture, ensuring consistent reliability even in challenging industrial environments.

Design and Benefits

The SIMOTICS S-1FK7 High Dynamic motors are engineered with a low rotor moment of inertia to enable rapid acceleration and deceleration, providing exceptional dynamic response. Their compact frame design allows for space-saving installation and easy integration into existing systems. In contrast, the High Inertia versions offer superior control stability and robustness against load variations, minimizing the need for manual tuning.

The natural cooling system ensures efficient heat dissipation without the need for external fans, contributing to long service life and reduced maintenance. These motors are widely used in applications such as machine tools, robotics, packaging, plastics, printing, and textile machinery, as well as in wood, glass, and ceramics processing. The 1FK7044-4CF71-1QB2 stands out as a premium solution for precise motion control, ensuring smooth, efficient, and reliable performance.
