What this motor is on the line
The 1FK7043-7AH71-1FH0 is a Siemens 1FK7-series high-dynamic synchronous servo motor — the compact high-inertia class that pairs with SINAMICS S110/S120 drives on packaging, pick-and-place, and feed-roller stations where a high torque-to-inertia ratio matters more than continuous stall torque.
Lifecycle read: EOL/hot
The ledger carries = eol_hot for this order code — Siemens has it on the discontinuation watch list, which is why independent-channel sourcing matters: the standard factory-direct catalog is thinning out, and last-time-buy decisions usually get driven by the drive-side firmware revision that pairs with this frame.
Sourcing posture for an EOL/hot code
For a code flagged EOL/hot, the realistic supply path is independent distribution — surplus and broker channels carry new-old-stock lots, with quantity, condition (factory-sealed vs refurbished), and current pricing all confirmed against the RFQ rather than off a price list.
