1FK7043-4CK71-1CG2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7043-4CK71-1CG2 is a compact, high-performance synchronous motor engineered for precision motion control applications. Delivering a rated power of 1.3 kW with a continuous torque of 3.5 Nm and a nominal speed of 6000 rpm, this motor ensures efficiency, accuracy, and superior dynamic performance in industrial environments. Featuring a natural cooling system and a robust IMB 5 flange design, it supports flexible installation in vertical or horizontal positions. The integrated 24-bit + 12-bit multi-turn absolute encoder with DRIVE-CLiQ interface provides exceptional positioning accuracy and seamless integration with SINAMICS drive systems. Designed with a plain shaft and IP65/IP67 protection, the motor guarantees long-term reliability even in challenging production conditions.

Overview

The SIMOTICS S-1FK7 series represents Siemens’ excellence in compact synchronous motor technology. Designed as permanent-magnet motors, the series offers versatile options including multiple encoder systems, gear configurations, and mechanical interfaces. This flexibility allows the SIMOTICS S-1FK7 motors to be tailored precisely to different automation requirements. When combined with SINAMICS S120 or S220 drive systems, they form a highly dynamic motion solution capable of precise speed and position control. Each motor is optimized for direct surface cooling, reducing the need for external fans and enhancing energy efficiency. The result is a compact and durable design suitable for modern, high-speed machinery.
