Part identity and what it is
The 1FK7040-2AK71-1CH1 J09 is a Siemens compact synchronous servo motor in the 1FK7 family, ordered under that exact order code for integration into a SINAMICS-driven motion axis. It sits in the Servo Motors subcategory under Motors & Motor Controls — the class used where a drive commands a closed-loop position or velocity axis on a machine.
Sourcing posture for this order code
For a project milestone or a line-down spare on an installed 1FK7040-2AK71-1CH1 J09, the realistic path is a broker / independent surplus quote rather than a factory-direct reorder, given the eol_hot status.
