1FK7043-4CH71-1RH1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CH71-1RH1 SIMOTICS S Synchronous Motor is an advanced high-performance servo motor engineered for precision, efficiency, and reliability. With a rated power of 1.2 kW, a rated torque of 3.5 Nm, and a rated speed of 4500 rpm, this naturally cooled motor is designed for continuous operation under demanding industrial conditions. Its compact frame (IMB 5 / IM V1 / IM V3) and rotatable power connector allow flexible installation across different machine configurations. The integrated AM20DQI absolute encoder provides 20-bit + 12-bit multiturn resolution with a DRIVE-CLiQ interface, ensuring precise position and speed feedback. Built to the rigorous IP65 protection standard, this unit delivers durability and reliability even in harsh environments.

Overview

The SIMOTICS S-1FK7 motor series represents Siemens’ commitment to innovation in high-performance synchronous motion control. Designed with permanent-magnet technology, these motors combine compact size with exceptional torque density, making them ideal for modern automation systems. They can be seamlessly paired with SINAMICS S120 or S220 drives to form a powerful and flexible motion solution. The heat generated during operation is dissipated through the motor housing, enabling efficient temperature control without the need for external cooling. With their modular design, various encoder options, and multiple shaft configurations, the 1FK7 series provides unmatched adaptability for diverse industrial tasks.

Design and Benefits

The 1FK7043-4CH71-1RH1 belongs to the High Dynamic variant of the SIMOTICS S family, featuring a low rotor moment of inertia for extremely responsive acceleration and deceleration. This enables superior precision in dynamic applications such as robotics, CNC machinery, and automated handling systems. For users requiring stability with varying load inertia, the High Inertia configurations ensure smooth, controlled motion. Other benefits include minimal commissioning time, easy integration with Siemens automation systems, and a space-saving design that optimizes installation within compact control cabinets.

Typical applications include machine tools, packaging machines, textile machinery, robotic arms, and precision assembly systems. Its combination of efficiency, compactness, and adaptability makes it a long-term investment for any advanced industrial environment.
