Siemens 1FK7 servo, 2.27 kg — what drops out of the catalog
The 1FK7032-5AK71-1AA3: Servo motors in this class are the actuator end of a closed-loop position/speed chain — encoder feedback back to the drive, drive commanding torque via the fieldbus — so the motor selection is inseparable from the drive catalog, shaft height, and resolver/encoder variant on the BOM.
Lifecycle reads hot end-of-life, not retired
The catalog listing carries eol_hot for 1FK7032-5AK71-1AA3 — Siemens has flagged the part on the warm side of its retirement curve, which typically means last-time-buy planning is already in motion and new-build projects should be evaluating the successor variant while MRO stock is still quotable. For a buyer holding a working axis on this code, the practical picture is that the motor will be available through independent surplus and authorized channels while factory stock drains — independent distribution quotes per RFQ against the part number, with lot-specific availability confirmed at quote time rather than a standing-stock claim.
