Compacted servo spindle on a Siemens SIMOTICS S machine
The 1FK7022-5AK74-1SG0 is a Siemens 1FK7 compact synchronous servo motor — the low-inertia building block of the SIMOTICS S family used in tight-axis packaging, dosing, and pick-and-place cabinets where the motor length has to stay short without giving up dynamic response.
Lifecycle read — end-of-life hot phase, the surplus clock is running
The catalog entry marks this 1FK7-derivative as EOL hot, which means the original Siemens production run has wound down and inventory is moving through independent channels rather than fresh factory shipments — quote every replenishment against an RFQ because lot stock and condition vary manifest to manifest.
Sourcing posture for a line-down servo
For a maintenance spares position on a packaging or assembly line that already runs 1FK7 hardware, the practical path is to source the 1FK7022-5AK74-1SG0 quote-to-order from independent distribution: confirm the encoder variant and shaft detail on the nameplate against the existing axis before cutting the PO, since eol-hot stock frequently carries mixed date codes.
FAQ — production status, supply channel, and core ratings
Independent distributors typically quote this Siemens 1FK7 servo motor to order against the BOM, with price, lot condition, and remaining stock confirmed at RFQ rather than at a published price.
