What this motor is and where it sits in the SINAMICS line-up
The 1FK7042-5AF71-1PH3 is a 1FK7 COMPACT SYNCHRONOUS MOTOR in the Siemens SERVO MOTORS family, listed under the Motors & Motor Controls → Servo Motors category — the compact 1FK7 frame is the short-stack, high-dynamics option typically paired with a SINAMICS S120 drive on machines where positioning accuracy and torque density both matter. A permanent-magnet synchronous servomotor of this frame is built around a resolver or encoder feedback loop on the drive side, which is why the order-code suffix (the -1PH3 segment) carries the encoder / shaft / holding-brake permutation — drop the motor onto the matching SINAMICS drive topology and the controller handles the commutation and the safety stop without further wiring.
Why the eol_hot flag changes the procurement decision
For a spare-parts buy this shifts the sourcing question: confirm the encoder variant on the nameplate (the -1PH3 suffix is the differentiator, not the frame), then pull an RFQ against the available independent stock — lead time and pricing are confirmed at quote rather than off a published lead-time ladder.
