What the line-down engineer is looking at
The 1FK7044-4CH71-1QA0 is the Siemens 1FK7 high-dynamic synchronous motor: a brushless servo paired with a SINAMICS-class drive, used where the machine cycle demands the kind of acceleration and positioning bandwidth a standard induction motor cannot deliver.
Frame size and what 7.26 kg does to the install
The mating half on a Siemens 1FK7 is the resolver or absolute encoder feedback and the power cable from the SINAMICS S120 drive line — so any panel that already runs an S120 drop-in keeps its existing connector set and parameter slot.
Sourcing posture for an EOL/Hot servo
An EOL/Hot 1FK7 is the classic last-time-buy / surplus scenario: the original Siemens production line has closed out this variant, and the supply channel is whatever independent stock is still traceable on the market. Quotations are built against the specific BOM position — quantity, traceability expectation, and whether a repair exchange or a new-in-box unit is acceptable all factor into the RFQ response, because EOL stock is lot-specific and the available quantity varies with each pull.
