Part identity and 1FK7 positioning
The 1FK7044-7AH71-1EG0 is a Siemens 1FK7 high dynamic synchronous servo motor, catalogued in the Servo Motors line and identified by part number 1FK7044-7AH71-1EG0.
Lifecycle flag and what it means for a running line
For a line still turning with this motor, that flag is the cue to set a last-time-buy quantity and route spares through independent distribution before the OEM channel thins further; for a new design, it is the cue to pick the current-generation 1FK7 variant or the matched SIMOTICS family rather than committing a fresh BOM line to an EOL/hot part.
Sourcing posture for a hot-phase servo
Encoder resolution, winding code, brake option, and shaft detail are not on this spec row, so confirming the full MLFB against the drive project on the cabinet drawing is the step that prevents a near-match 1FK7 from landing as a wrong-encoder spare.
