Where this motor belongs in the machine
The Siemens 1FK7040-2AK71-1AG0 is a 1FK7 compact synchronous servo motor intended for high-dynamic positioning axes — packaging lines, small CNC feeders, indexing tables, and similar motion loads where the 1FK7 series delivers the torque density a SIMOTION or SINAMICS S120 drive expects on a controlled axis.
Lifecycle read — what EOL/HOT means for the BOM
For a buyer this typically means a last-time-buy window for ongoing production machines, and for installed-fleet maintenance a sourcing plan that quotes per-RFQ against available surplus or factory-remnant stock — pricing and lead time confirmed at quote time, no off-the-shelf availability assumed.
Checking the wiring before you ship anything back
On a returns desk the first step with any 1FK7 is to confirm the resolver or encoder feedback wiring against the SIMOTION/SINAMICS drive configuration and the shielding/grounding at the motor connector — most servo-motor returns we see trace back to a feedback or shield-drain issue, not a winding failure, and the original packaging is worth keeping if a return is genuinely required.
