Siemens 1FK7040-5AK71-1AG2 in the SINAMICS S120 drive line
The Siemens 1FK7040-5AK71-1AG2 is a synchronous servo motor from the SINAMICS S120 family, sized for the high-dynamic positioning axes typically served by 1FK7 compact motors — feed axes, auxiliary spindles, and small-format machine-tool slides where torque density at low speed matters more than continuous stall rating.
Sourcing posture through independent distribution
With the part flagged EOL hot, the realistic sourcing path is independent distribution quoting against an RFQ: surplus stock traceable to the original Siemens build, with each unit's date code and condition confirmed at quote time. Lead times on lots already pulled from the channel are typically shorter than a factory re-order, but quantity is lot-specific and not guaranteed across multiple RFQs.
