Siemens 1FK7 compact synchronous servo motor in the 1FK7042 frame
The Siemens 1FK7042-5AF71-1DA0 is a 1FK7 compact synchronous servo motor, the brushless permanent-magnet type used as a rotary axis drive on machine tools, packaging lines, indexing tables and similar servo-positioning axes. The synchronous rotor design and integrated encoder feedback make it a closed-loop position actuator paired with a SINAMICS S120 or SIMOTION drive line.
EOL status and what that means for replacement stock
Lifecycle stage is recorded as eol_hot: the part is past its active manufacturing window and is sustained through remaining inventory and independent distribution rather than new factory runs. For a buyer filling a spare slot this is the cohort where lot-specific surplus and factory-traceable overhauls carry the line — quoted against an RFQ, no immediacy or volume claim made here.
