1FK7044-4CH71-1QA2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7044-4CH71-1QA2 SIMOTICS S Synchronous Motor represents a new standard in industrial motion performance, designed to deliver efficiency, precision, and reliability across multiple automation environments. With a rated power of 1.4 kW and torque output of 4.5 Nm, this motor ensures stable and responsive operation even under challenging load conditions. Operating at a rated speed of 4500 rpm and powered by a 600V DC link, it is perfectly suited for demanding applications that require high dynamic response and consistent accuracy. The unit features an absolute single-turn 20-bit encoder with DRIVE-CLiQ interface (AS20DQI) for enhanced position feedback, as well as a rotatable power connector for flexible installation.

Overview

The SIMOTICS S-1FK7 motor series combines compact construction with high power density, making it ideal for modern machines that demand both performance and efficiency. The 1FK7044-4CH71-1QA2 model is part of the High Dynamic (HD) line, featuring low rotor inertia for faster acceleration and precise motion control. Its robust design, protection class of IP65/IP67, and maintenance-free operation make it ideal for environments where reliability and uptime are critical. The motor dissipates heat naturally via its housing, eliminating the need for external cooling, thus simplifying the overall system design.

Design and Applications

Compact and energy-efficient, this motor can be combined seamlessly with SINAMICS S120 or S220 drive systems to form a powerful automation solution. The unit’s rugged construction supports IMB5 mounting formats and includes a keyed shaft with tolerance N, ensuring optimal mechanical stability. Designed for universal industrial use, it offers excellent closed-loop control properties suitable for applications with variable inertia loads. Typical use cases include machine tools, robotics, packaging systems, woodworking machinery, and printing equipment. Its precision and quick response make it ideal for tasks requiring superior motion control and dynamic performance.

With extended compatibility, scalability, and an intelligent encoder interface, the 1FK7044-4CH71-1QA2 motor delivers premium Siemens quality and is a key component in high-accuracy production lines and automated systems worldwide.
