Identifying the 1FK7 high-dynamic servo on the nameplate
The part is a Siemens 1FK7 high-dynamic synchronous servo motor carrying order code 1FK7044-7AH71-1KG3, catalogued under servo motors within the broader motors and motor controls class. 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.
