Product details

High-dynamic synchronous servo for precision axes

The Siemens 1FK7044-7AH71-1AH3 is a high-dynamic synchronous servo motor from the 1FK7 family, the compact low-inertia class typically paired with SIMOVERT MASTERDRIVES or SINAMICS drives in feed axes, indexing tables, and packaging machines where rapid acceleration and deceleration profiles are the design constraint.

Lifecycle posture — EOL, sourced on RFQ

The part carries an EOL/hot lifecycle flag, which means the OEM line is closed and new units are only available through independent distribution channels — what the buyer needs is a quoted-to-order posture with manufacturer-traceable stock confirmed against the specific RFQ quantity, not a normal franchised-channel assumption.

Frequently asked questions

Where can I buy 1FK7044-7AH71-1AH3 and how do I get a price?

Source through independent industrial-automation distribution on an RFQ basis. Lead time and current pricing are confirmed against the order quantity at quote time; manufacturer traceability and date-code records are supplied with the quote so the buyer can verify what they are receiving.

What's the listed weight of 1FK7044-7AH71-1AH3?

8.16 kgs, per the manufacturer specification — the same mass figure carried by the closest 1FK7044-frame peer, confirming a shared frame size across that suffix block.

Can 1FK7044-7AH71-1AH3 be swapped for 1FK7044-7AF71-1KB0 without rewiring?

The shared 8.16 kg mass and 1FK7044 frame family indicate a common mechanical envelope, so mounting, shaft height, and footprint align. However, the winding designation, encoder option, and connector variant are encoded in the suffix block and are not identical between the two order codes — the electrical and feedback pinouts need a side-by-side check against the original wiring diagram before a drop-in substitution is committed.
