SINAMICS S120 servo motor, EOL/hot
The Siemens 1FK7040-5AK71-1EG0 is a SIMOTICS 1FK7 synchronous servo motor built for the SINAMICS S120 drive family — the compact, high-dynamics brushless servo class Siemens sells into machine-tool spindles, packaging indexers, and pick-and-place axes.
What 3.18 kg means at the shaft
Servo motors in the 1FK7 frame range typically pair resolver or absolute encoder feedback and integrate into the SINAMICS S120 drive line through the DRIVE-CLiQ wiring convention — confirm the encoder variant on the nameplate before commissioning, since feedback type is set at order time and not field-swappable without a drive-side parameter change.
Sourcing posture for a part out of factory production
With the part carrying an EOL/hot lifecycle flag, the realistic path is independent distribution quoting against an RFQ: surplus and factory-residual stock checked at the order level, lead time confirmed at quote time, and lot traceability preserved through the declaration pack on shipment.
