Where this motor drops in
The 1FK7022-5AK71-1HG5 is a 1FK7 COMPACT synchronous servo motor from the Siemens servo line — the short-frame brushless unit sized for high-dynamic positioning axes in machine tools, packaging lines, and small-format indexing tables where the drive electronics are already a SINAMICS S120 or SIMOTION controller.
Lifecycle read
Lifecycle is flagged EOL/hot — the 1FK7022-5AK71-1HG5 is past its standard production run and new-build orders no longer flow through the regular Siemens channel, so a BOM position that specified it must be backstopped through surplus or independent distribution rather than a fresh factory shipment. The Siemens 1FK7022-5AK71-1HG5 is not a stock-keeping commodity — each enquiry is quoted against the current broker and authorised-channel inventory, and lot-specific date codes are confirmed at RFQ.
Sourcing posture
For a line-down spare or a running change-out, the practical path is independent distribution — nameplate, feedback type, and brake option on the incoming unit should be matched against the old nameplate before the encoder cable is terminated, because the 1FK7022-5AK71-1HG5 suffix encodes the winding, holding brake, and connector variant that the SINAMICS drive topology expects at first commissioning.
