Lifecycle read and why it matters
The catalog lists 1FK7086-4SF71-1CA0 at lifecycle stage eol_hot, so the active Siemens channel has wound down for this code — independent surplus and the last factory-traced lots are the realistic supply path, with quantity confirmed per RFQ.
Headline ratings and what they drive
The motor is rated 38 Nm continuous, 100 K thermal class, 3000 RPM, and 7.50 kW with forced ventilation — that combination sets the shaft-load envelope, and the fan means continuous-torque output is available beyond what an unventilated 1FK7 frame would deliver at standstill.
Mechanical fit and what to plan for
Flange is IM B5 (V1, V3), shaft is supplied with a fitted key at tolerance N, and the power/signal connectors rotate 270° — that rotatability is what clears the cable entry on retrofits where the original motor was installed back-to-back with a gearbox or brake assembly. Despite the Servo Motors with Brake category trail, this code is specified WITHOUT a holding brake — the absence matters for any safety-rated axis because a vertical or gravity-loaded application cannot rely on the motor itself to hold position when the drive is disabled. Degree of protection is IP64 — sealed against splash and dust ingress, but not rated for high-pressure washdown, so this code fits a general machine-room or panel-side environment rather than a food-and-beverve line that hoses down. The build is a custom variant per SMR-31-2015, which is why the code carries a 1CA0 suffix rather than a standard catalog suffix — any replacement must be sourced against the same variant designation, not the equivalent catalog motor, because the option codes are part of the build record.
