Which Siemens servo motor is this, and why does the order code matter
The 1FK7044-7AH71-1EH5: The order code is what locks the motor's electrical length, winding, feedback, and shaft/sealing options to a single BOM line — substituting a 1FK7044 sibling that differs only in the winding or feedback suffix will not drop into the same drive parameter set without a fresh commissioning pass.
Where this part stands on the lifecycle clock
On an eol_hot servo, the procurement question is not whether the motor still exists on the world market — it does — but whether each unit traces back to a Siemens production batch with intact feedback device calibration and a clean nameplate-to-PO paper trail, which is exactly the gap that independent sourcing has to close for a commissioning engineer.
Sourcing posture for a motor the OEM has wound down
Genuine is genuine regardless of which authorized region the 1FK7044-7AH71-1EH5 left — same part, different passport — so the buyer's actual decisions on an EOL servo like this are provenance (factory batch, date code, original Siemens packaging vs. repack), warranty geofencing against the Siemens regional service organization, and whether the SINAMICS drive's firmware parameter set already in the cabinet will accept the motor's stored electronic nameplate without a re-commission.
