Position in the SIMOTICS 1FK7 high-dynamic line
The 1FK7044-7AH71-1DH0 is a Siemens 1FK7 high-dynamic synchronous servo motor in the SIMOTICS family, built around a permanent-magnet rotor for high-acceleration motion axes where short cycle times and low rotor inertia matter more than continuous torque.
Lifecycle read: EOL hot and what that means for the BOM
For a procurement plan that means de-risking the supply base before that window narrows: confirm quantity and lead time against an RFQ now rather than treating the line as indefinitely available, and budget a board-level or motor swap to a current 1FK7 variant if the line is a long-cycle design-in.
Sourcing posture for a hot EOL servo motor
Independent distribution is the realistic channel here: traceable surplus, factory-pull, and repair-exchange lots vary in quantity, so each RFQ returns a different envelope — that is normal for an EOL hot motor and is why the BOM position needs a hard quote rather than a held-inventory assumption.
