1FK7 high-dynamic motor, currently EOL — what that means for the BOM line
The 1FK7061-4CH71-1RH0 is a 1FK7-series high-dynamic synchronous servo motor in the Siemens Servo Motors line, with the manufacturer flagging this order code as EOL — the part is no longer in normal production, so the only reliable supply path is independent distribution and quoted last-time-buy / surplus lots, not a factory PO.
Sourcing posture for a project that still needs this order code
For a buyer chasing a replacement motor, the EOL read means no factory-direct replenishment — the order code is sourced against current independent-channel stock, with quantity, traceability and current unit pricing confirmed at RFQ; budget this as a commissioning-window risk, not a standard line item, because each lot is finite and lot size is not guaranteed across multiple calls.
Where a 1FK7 high-dynamic motor sits on the line
As a high-dynamic synchronous servo, the 1FK7 is used in motion axes where rapid acceleration and deceleration with low torque ripple matter — packaging, machine tool feed, indexing tables, and pick-and-place axes are the typical deployments, paired with a Siemens SINAMICS drive on the same PROFINET / PROFIdrive control loop; the EOL status on this specific order code does not change that machine-side role, it only changes how the part enters the BOM.
