1FK7043-4CH71-1CG0 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New
The SIEMENS 1FK7043-4CH71-1CG0 belongs to the renowned SIMOTICS S-1FK7 series of synchronous motors, engineered for precision, durability, and compact performance. With a rated power of 1.2 kW and a torque output of 3.5 Nm, this motor delivers exceptional efficiency and stability for high-performance automation environments. Operating at 4500 rpm with a 600 V DC supply, the motor is designed with a naturally cooled structure and IP64 protection, ensuring long-term reliability even in demanding industrial conditions. Its rotatable power connector and AM24DQI encoder with 24-bit + 12-bit multiturn capability enable accurate position control and seamless communication through DRIVE-CLiQ interface technology.
Overview
The SIMOTICS S-1FK7 motors are compact, permanent-magnet synchronous motors designed to meet the evolving demands of modern automation. Their modular configuration allows integration with various encoders, gear units, and cooling types, making them highly adaptable to a wide range of applications. When paired with SINAMICS S120 or S220 drive systems, these motors deliver a complete motion control solution with superior precision and dynamic response. Their construction supports operation without external cooling, dissipating heat efficiently through the motor surface for consistent performance and low maintenance requirements.
Benefits and Applications
The SIMOTICS S-1FK7 series offers multiple design variants including Compact, High Dynamic, and High Inertia models—each suited for specific operational needs. The Compact model minimizes installation space while maintaining high power density; the High Dynamic version provides fast acceleration through low rotor inertia; and the High Inertia model ensures stable control in applications with variable load torque. Typical applications include machine tools, robotics, handling systems, and machinery used in wood, glass, packaging, and textile industries. These motors provide a reliable foundation for advanced motion systems where accuracy, speed, and endurance are essential.
