1FK7043-4CK71-1BH1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CK71-1BH1 is a high-performance synchronous motor designed for demanding automation and motion control applications. This precision-built motor offers a nominal power of 1.3 kW and operates with a DC link voltage of 600 V, delivering a torque of 3.5 Nm and a maximum speed of 6000 rpm.

Its naturally cooled structure and robust IMB 5 (IM V1, IM V3) flange configuration ensure efficient thermal management and durability under continuous operation. With an integrated 24-bit single-turn absolute encoder and DRIVE-CLiQ interface, this motor enables precise position feedback and seamless integration with SINAMICS drive systems. The inclusion of a holding brake and IP65 protection further enhances operational safety and reliability, making it suitable for a wide range of industrial environments.

Overview

The SIMOTICS S-1FK7 series represents Siemens’ advanced generation of permanent-magnet synchronous motors. Known for their compact size and high power density, these motors are designed for flexibility and superior dynamic performance. They can be combined with SINAMICS S120 or S220 drive systems to form a complete, high-functionality motion control solution. The integrated encoder systems allow accurate speed and position control, while the efficient heat dissipation through the motor housing eliminates the need for external cooling. With an extended range of variants, including High Dynamic and High Inertia models, the SIMOTICS S-1FK7 motors can be tailored precisely to the mechanical and operational needs of modern automated machinery.
