The 1FK7044 frame is the compact high-dynamic member of the 1FK7 family — a brushless synchronous servo driven from a Siemens SINAMICS or SIMOTION drive line — and the suffix string selects the winding, feedback, brake and connector options for that specific build. ## Lifecycle posture and what it means for the BOM line The manufacturer is Siemens and the part sits in the 1FK7 series, so the official nameplate, type-test data and conformity documentation are issued under the Siemens product brand; any declaration of conformity, RoHS/REACH statement, or functional-safety data the buyer needs is sourced against the Siemens build record for the 1FK7044 frame, with the order-code suffix identifying the specific variant. ## Sourcing path for an EOL servo on a live line A compliance buyer signing off the part into a controlled build needs the Siemens declaration of conformity for the 1FK7044 frame and the variant-specific nameplate data stamped on the motor housing; the order-code suffix is the key that ties the unit back to the Siemens build record for that variant.","metaTitle":"Siemens 1FK7044-7AH71-1KG3 Servo Motor, 3.49 kg","metaDescription":"Siemens 1FK7044-7AH71-1KG3 1FK7 high-dynamic synchronous servo motor, 3.49 kg, EOL/hot lifecycle.
