Product details

Identity and class

The Siemens 1FK7044-7AH71-1EA2 is a 1FK7 high-dynamic synchronous servo motor in the Siemens synchronous-servo line, ordered as part number 1FK7044-7AH71-1EA2. It sits in the Servo Motors category — a compact brushless servo used on machine axes where high dynamic response and short positioning cycles are the design driver, typically paired with a Siemens SINAMICS S120 drive on a multi-axis line.

Lifecycle read — eol_hot, not active stock

Buyers in this phase should treat every quote as lot-conditional — date code, packaging seal, and resolver/encoder option must match the BOM line, not just the order code.

Frequently asked questions

Will 1FK7044-7AH71-1EA2 drop into a panel that was specified around 1FK7042-5AF21-1UA0 without rewiring?

Not as a direct swap. The two share the 1FK7 family but the 1FK7044 frame is a different shaft height/stack-length envelope from the 1FK7042 peer at 4.54 kg — cable lengths, mounting footprint, and encoder option all need to be checked against the original wiring diagram before substitution.
