1FK7043-4CH71-1QB2 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS 1FK7043-4CH71-1QB2 SIMOTICS S Synchronous Motor represents the next generation of high-efficiency motion technology designed for modern automation. With a rated power output of 1.2 kW and a nominal torque of 3.5 Nm, this motor delivers outstanding precision and performance across a wide range of industrial applications. Operating at a nominal speed of 4500 rpm and a rated voltage of 600 V DC, the unit provides smooth and responsive torque characteristics ideal for high-performance machinery. The compact, naturally cooled design ensures efficient heat dissipation through its frame surface, reducing energy loss and maintaining operational stability in demanding environments.

Built with a rotatable power connector and an absolute encoder single-turn 20-bit with DRIVE-CLiQ interface (AS20DQI), this motor enables precise position feedback and seamless integration with SINAMICS S120 or S220 drive systems. The robust mechanical structure, featuring a fitted key shaft and integrated holding brake, ensures excellent durability and safety. With protection degrees of IP65 (housing) and IP67 (flange), this synchronous motor is engineered for long-term reliability even in dusty or moisture-prone environments. It is a trusted choice for advanced automation systems requiring high precision and continuous duty performance.

Overview
