Description

1FK7043-4CK71-1RB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CK71-1RB2 SIMOTICS S Synchronous Motor is a high-performance permanent-magnet motor engineered for precision motion control in industrial automation systems. With a power rating of 1.3 kW and a rated torque of 3.5 Nm, this model provides smooth and accurate performance across a wide range of applications.

It operates at 6000 rpm and uses a 600V DC supply, making it ideal for compact machines that require powerful yet efficient drive technology. The motor features a natural cooling system with a rugged IMB 5 (IM V1, IM V3) flange construction, ensuring durability and long life under continuous load. Its absolute encoder with 20-bit + 12-bit multi-turn DRIVE-CLiQ interface delivers precise feedback, while the integrated holding brake and IP65/IP67 protection provide robust reliability in demanding environments.

Overview

The SIMOTICS S-1FK7 motor family represents Siemens’ advanced generation of synchronous servo motors. Designed for flexibility and performance, these compact motors are available in multiple configurations and can be paired seamlessly with the SINAMICS S120 or S220 drive systems. The combination provides high-precision speed and position control, optimized for automation and motion systems requiring fast response and superior control accuracy. With their naturally cooled housing and high overload capacity, the motors deliver consistent performance even in challenging thermal conditions.

Benefits

  • Compact design with exceptional power density for space-saving installation.
  • Flexible integration into various industrial machines and automation systems.
  • High dynamic response through lightweight rotor design.
  • Reliable closed-loop control for demanding load variations.
  • Reduced setup and commissioning effort due to integrated encoder options.
