Siemens 1FK7034-2AK71-1QA0 Servo Motor With Encoder

Siemens SIMOTICS S synchronous motor 1FK7034-2AK71-1QA0 is a compact 0.63 kW servo motor in the 1FK7 family, designed for precise motion control and high-torque routines in automation. Operating from a 600 V DC bus, it delivers M0 of 1.6 Nm and a nominal speed of 6,000 rpm, with natural convection cooling in the IMB 5 construction (IM V1/IM V3) and a standard flange size designated by the 1AK71 series. A rotatable power connector supports flexible mounting, and the unit uses an integrated encoder system: a single-turn absolute encoder with Drive-CLiQ interface (AS20DQI) providing 20-bit feedback resolution. The encoder arrangement provides precise position information for closed-loop control, aiding repeatability in high-speed positioning tasks. The motor features a shaft with a feather key and a 20-bit encoder that integrates with drive electronics for streamlined servo systems. The seal and housing meet IP64 protection, appropriate for general industrial environments. The 1FK7034-2AK71-1QA0 is a good fit for automated machinery requiring reliable, high-precision synchronous motion with Siemens drive ecosystems and SINAMICS-compatible servo control.
