What this motor is on the BOM
The 1FK7042-5AK71-1FH0 is the 1FK7 compact synchronous servo motor from Siemens — a permanent-magnet synchronous drive used where a small-frame servo has to hold position, run a tight velocity loop, or follow a high-dynamics profile on a machine axis. It sits in the Servo Motors line and pairs with a Siemens SINAMICS-class drive on the cabinet side, feeding back resolver or encoder position through the motor-mounted feedback connector.
Lifecycle read on the line
For an MRO buyer replacing a failed unit on a running machine, that translates into lot-specific availability: each quoted piece comes from a specific reel or surplus lot with its own date code, and lead time is set by what the market currently holds, not by a factory schedule.
Sourcing posture
Independent distribution carries the 1FK7042-5AK71-1FH0 against an RFQ — current pricing and lot availability are confirmed at quote time, with traceability back to the original Siemens reel rather than the OEM order pipeline.
