Lifecycle read on 1FK7086-4SF71-1CB0
Per the specification, this is a custom-built motor as per SMR-31-2015 — the 'custom made' note inside the order code description reinforces that even before the EOL flag, units were made against a specific variant sheet rather than a stock catalog item, so the supply pool is historically narrow.
What the SIMOTICS S 1FK7 build delivers
As listed, the motor is a 1FK7086 frame SIMOTICS S high-dynamic servomotor rated 38 Nm at 100 K with a rated speed of 3000 rpm and a shaft output of 7.50 kW, driven by forced ventilation rather than a self-cooled housing — meaning the cooling air must be supplied for the thermal envelope to hold the 38 Nm figure, and that auxiliary blower becomes part of the maintenance point, not just an option. The encoder is the 24-bit single-turn + 12-bit multiturn absolute encoder AM24DQi on a Drive-CLiQ interface, so the motor speaks the native Siemens drive-CLiQ protocol and pairs directly with SINAMICS S120 without an external resolver cable or third-party encoder card — a Drive-CLiQ-only motor is not retrofittable to a third-party drive without conversion hardware. The mechanical build is IM B5 flange mounting with rotatable power and signal connectors (270° indexing), a keyed shaft to tolerance N, and a degree-of-protection rating of IP64, which is the sealed-against-splashes rating — sufficient for an enclosure-mounted machine-tool axis but it is not the IP65 / IP67 washdown ceiling found on food-grade motors and should not be specified where jet-water exposure is normal. The order code carries no holding brake; a brake must come from the driven assembly rather than the motor itself, which means the vertical-axis hold function (if used on the original machine) is provided upstream of the gearbox or coupling — a buyer fitting this motor to a gravity-loaded axis must resolve the holding-brake question at the system level.
Sourcing posture for an EOL SIMOTICS 1FK7
Given eol_hot on this 1FK7086-4SF71-1CB0, sourcing is a quoted-to-order exercise rather than a shelf-pull — RFQ is the only honest route to a confirmed quote, and lead time depends on what is on hand at the time of enquiry rather than a published catalog number.
