Siemens SIMOTICS S-1FK7 Compact Servo Motor About

The Siemens SIMOTICS S 1FK7042-5AF71-1PH3 is a compact three-phase permanent-magnet synchronous servo motor belonging to the SIMOTICS S-1FK7 family. The exact MLFB is documented in Siemens product-family records and industrial databases. The motor is designed for precision motion-control applications such as CNC machinery, machine tools, robotics, packaging equipment, automated assembly and industrial automation. Its compact construction provides high dynamic response, accurate positioning and reliable operation when paired with a compatible Siemens SINAMICS drive. The 1PH3 configuration is one of the resolver/feedback variants within the 1FK7042-5AF71 family. Because publicly indexed sources do not expose the complete Siemens technical sheet for this exact suffix, feedback, brake, weight and some electrical values should not be treated as confirmed without the original Siemens MLFB datasheet. Siemens documentation lists the exact 1FK7042-5AF71-1PH3 as a SIMOTICS S product.
