1FK7043-4CH71-1QG2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CH71-1QG2 SIMOTICS S Synchronous Motor is a high-performance servo motor engineered for precision, durability, and efficiency in modern automation systems. Designed with a nominal power of 1.2 kW and a rated torque of 3.5 Nm, this motor achieves up to 4500 rpm, ensuring exceptional dynamic response and accuracy. The rotatable power connector and absolute single-turn encoder (AS20DQI) with DRIVE-CLiQ interface enable flexible integration and reliable feedback for closed-loop control. With a naturally cooled design and IP65/IP67 protection, this motor delivers long-term reliability even in challenging industrial conditions.

Overview

The SIMOTICS S-1FK7 series represents Siemens’ advanced line of compact, permanent-magnet synchronous motors. These motors are designed for maximum adaptability, offering a wide range of mechanical and electrical options such as gearboxes, encoders, and frame sizes. The 1FK7043-4CH71-1QG2 variant is optimized for direct compatibility with SINAMICS S120 and S220 drive systems, forming a powerful automation solution capable of high-speed positioning and efficient energy conversion. Integrated encoder systems ensure precise motion control and consistent performance in dynamic industrial environments.

Design and Benefits

The motor’s compact structure allows for space-saving installation and high power density, making it ideal for both compact and high-load applications. Its plain shaft with tolerance N provides stable mechanical connection, while the absence of a holding brake supports continuous motion operations. The high overload capacity and naturally cooled aluminum frame ensure long service life with minimal maintenance. With its robust mechanical build and flexible configuration, this model is suitable for machine tools, robotics, packaging systems, printing, and material handling equipment.
