What the listing carries
The part on the BOM is the Siemens 1FK7044-4CH71-1QH0, a 1FK7 high-dynamic synchronous servo motor in the Motors & Motor Controls → Servo Motors class. The 1FK7 family is the high-dynamic compact servo line designed for short-cycle, high-acceleration axes in packaging, handling, and machine-tool duty.
Sourcing posture for an EOL servo
For an OEM running 1FK7044-4CH71-1QH0 on the BOM, the realistic question is fleet coverage rather than spot replacement — count the installed axes, lock in the quantity that covers the next service window, and decide whether a re-engineer to a current 1FK7 variant is on the table before the surplus pool thins.
