Definition and what the part does
A 1FK7-series high-dynamic synchronous servo motor — Siemens' compact, high-inertia rotor family sized for machine-tool feeds, packaging axes, and small-format converting lines where the drive demands a snappy torque-to-inertia ratio. The 1FK7033-7AK71-1HH5 is the specific shaft/winding/encoder configuration under this frame size. It sits in the Servo Motors category (top-level Motors & Motor Controls) and pairs with a SINAMICS-class drive on a third-party motion controller or a SIMOTION/S7-based axis; the motor carries its position feedback on the encoder connector, not the power connector, so the cabinet-side wiring is a separate resolver/encoder cable.
Status of the line — what the lifecycle flag means here
The supported path off this frame is the 1FK7 successor generation — same frame footprint, updated winding codes and encoder interface. Buyers with active machines on the line who need a like-for-like spare should treat the eol_hot flag as a now-or-never window for matching spares, not a long-term stocking option.
Sourcing posture for an out-of-production servo motor
Lead time and lot availability are lot-specific for a retired frame; no stock-holding claim is made for this part.
