1FK7043-4CH71-1QG0 SIEMENS Exclusive High Performance Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CH71-1QG0 SIMOTICS S Synchronous Motor represents a premium solution for precise motion control and automation efficiency. Designed with a rated power of 1.2 kW and a nominal torque of 3.5 Nm, it offers consistent performance at speeds up to 4500 rpm. This naturally cooled motor, with IP64 protection and a robust frame IMB 5 (IM V1, IM V3), ensures reliable operation even in demanding environments. The integrated AS20DQI absolute encoder with DRIVE-CLiQ interface provides exceptional accuracy for both position and speed feedback, making it an ideal choice for precision-driven industrial applications.

Overview

SIMOTICS S-1FK7 motors are compact permanent-magnet synchronous motors that deliver outstanding efficiency and versatility. Engineered for seamless integration with SINAMICS S120 and S220 drive systems, they form a high-performance automation platform offering advanced motion control features. The 1FK7043-4CH71-1QG0 variant excels in applications requiring smooth dynamics and precise torque regulation. Thanks to its efficient heat-dissipation design, the motor can operate without external cooling, while maintaining high overload capacity and superior reliability under continuous use.

Design and Benefits

The SIMOTICS S-1FK7 family provides multiple configurations for diverse automation needs. The Compact series allows space-saving installation and universal usability across machinery types. High Dynamic variants deliver extremely quick acceleration due to a low rotor moment of inertia, while High Inertia models ensure stable control with variable loads. These design options minimize commissioning time and optimize system response, ensuring continuous precision with minimal maintenance. In addition, the motor can be paired with gearboxes and encoders to meet custom requirements across different industries.

Applications

This motor is widely used in machine tools, robotics, packaging, printing, plastics, textiles, and material-processing machines. Its compact form factor and high power density make it especially suitable for space-restricted installations where both precision and efficiency are critical.
