EOL-hot 1FK7 — why this order code is on every machine tool retrofit list
The 1FK7044-7AH71-1FB5 is a Siemens 1FK7 high-dynamic synchronous servo motor built for fast-acceleration axes — packaging, machine tool, and pick-and-place feeds where the rotor inertia has to stay low relative to the load. The listing carries eol_hot, meaning the order code is no longer in mainstream factory production and the available supply now sits in the independent channel.
What eol_hot changes for the BOM line
For a running line still specified around 1FK7044-7AH71-1FB5, the planning move is to lock several spares while the independent supply is still moving, because pricing and availability drift as the remaining lots thin out.
Sourcing posture for this 1FK7
Traceability documentation is provided with each shipment, and the unit price and lead time are confirmed at quote time — no standing inventory claim and no OEM-direct channel for this EOL-hot MPN.
