1FK7043-4CH71-1CB0 SIEMENS Exclusive High Dynamic Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S-1FK7 1FK7043-4CH71-1CB0 is a premium synchronous motor engineered for superior precision, energy efficiency, and long-term reliability in industrial automation. Designed as part of the renowned SIMOTICS S-1FK7 family, this high-dynamic model delivers 1.2 kW rated power with a continuous torque of 3.5 Nm and a nominal speed of 4500 rpm. It operates on a 600 V DC supply and is naturally cooled, eliminating the need for external cooling units. The motor’s robust IP64 protection and high-performance encoder AM24DQI ensure accurate feedback and consistent performance in demanding motion control environments. With its rotatable power connector, integrated holding brake, and flange mounting (IMB5 / IMV1 / IMV3), this unit is built to simplify installation and enhance operational safety.

Overview

The SIMOTICS S-1FK7 series represents Siemens’ latest generation of compact permanent-magnet synchronous motors. Each motor is designed to combine powerful torque with minimal space requirements, offering exceptional flexibility across a wide range of industrial applications. When paired with SINAMICS S120 or S220 drive systems, the 1FK7 motors create a high-performance drive package that ensures precise positioning, smooth motion control, and efficient operation under varying loads. Integrated feedback systems, available in multiple resolutions, allow the motor to adapt to complex automation demands and maintain high accuracy even during rapid acceleration or deceleration phases.

Benefits
