What the part is on the shelf
The 1FK7040-5AK71-1TG0 is a 1FK7 COMPACT SYNCHRONOUS MOTOR from Siemens, sitting in the Servo Motors class of the Motors & Motor Controls line. It is the rotating half of a closed-loop servo axis — paired with a Siemens SINAMICS or SIMOVERT drive on the cabinet side to close position and velocity loops on a machine tool, packaging line, or pick-and-place.
Lifecycle read — what eol_hot actually means
For a shop running a line with this motor in service, the practical meaning is: order what you need for the next two or three service windows now, because once the factory allocation is gone you move to independent surplus channels.
