1FK7040-2AK74-1EG1 SIEMENS Exclusive SIMOTICS S Synchronous Motor Original Brand New

The SIEMENS SIMOTICS S 1FK7040-2AK74-1EG1 is a premium synchronous motor engineered for precision, reliability, and versatility across a wide range of industrial automation systems. Designed with high-quality permanent-magnet technology, this model offers superior efficiency, reduced heat generation, and stable torque performance. With a nominal power of 0.69 kW and rated speed of 6000 r/min, it delivers smooth and consistent motion control ideal for demanding machine operations. The motor features a naturally cooled design, a plain shaft with tolerance N, and an IP65 protection rating, ensuring long-term durability even under tough industrial conditions.

This SIMOTICS S 1FK7 motor includes an absolute encoder (2048 S/R + 4096 revolutions) with EnDat interface, allowing precise feedback for optimal control accuracy. The rotatable power connector provides easy installation flexibility, while the absence of a holding brake makes it suitable for systems that require continuous motion and minimal mechanical resistance. Built to integrate seamlessly with SINAMICS S120/S220 drive systems, it enables advanced motion control functions such as coordinated axis movement, speed synchronization, and dynamic load response—making it the preferred choice for automation professionals seeking both reliability and performance.
