What the order code identifies
The Siemens 1FK7032-5AK71-1LH3 is a compact AC servo motor out of the 1FK7 family, the synchronous-servo line designed to run on Siemens SINAMICS S120 / S210 drive platforms in high-dynamic positioning and speed-controlled axes. It is a flange-mounted, naturally cooled rotary servo with an integrated absolute encoder — the option block in the 1FK7032-5AK71-1LH3 order code points to the specific shaft, holding-brake and connector configuration that distinguishes this variant from siblings in the same frame size.
Lifecycle read and what eol_hot means here
The 1FK7032-5AK71-1LH3 carries an eol_hot lifecycle flag, meaning Siemens has placed the order code on an active phase-out: production is winding down while service and spare-parts supply continue for a defined window, and new-build demand is expected to migrate to a successor within the 1FK7 family or to a 1FK2 / SIMOTICS S-1FK2 replacement.
Sourcing posture for a phase-out Siemens servo
Buyers specifying into a new machine should already be looking at the documented 1FK7 successor the order code maps to and qualifying that variant in parallel; buyers chasing a spare for an installed axis should match the existing order code against current allocations before accepting a generic '1FK7 replacement' quote, because the option code drives shaft, brake and encoder fit.
