Read this before you spec it on a new line
The 1FK7064-7AH71-1FH3: The part sits on the shelf as a Siemens 1FK7 high-dynamic synchronous motor — the frame that drives the fast, repetitive axes on packaging, converting, and machine-tool cells where the inertia has to come down hard and the cycle time can't.
What the phase-out flag means for the BOM line
Lifecycle reads eol_hot on this listing, which is the manufacturer's own 'stop ordering new designs, but keep the spare-parts channel moving' signal — for an active build this is a hard stop on new specification, and for an installed machine it shifts the spares strategy toward independent stocking now rather than later when the surplus pool thins out.
Integration checklist for a swap-in
Mounting is the standard 1FK7 flange pattern, so the mechanical swap onto an existing machine bed is straight-forward, but the encoder and brake connector keying has to match the SINAMICS drive being commissioned — the 1FK7 generation carries the multi-pole resolver and DRIVE-CLiQ interface variants under one frame code, and the suffix is what tells you which one you are holding.
