27 Nm / 4.87 kW frame in the 1FK7 Compact line
The 1FK7101-5AF7.-1... is a SIMOTICS S 1FK7 Compact synchronous servo motor — 27 Nm of static torque, 4.87 kW continuous output at 3000 rpm in naturally cooled (non-forced-vent) duty, with the power/signal connector plug rotatable by 270° for cabinet routing. Spec'd as a spare-part variant of the standard catalogue configuration, so the frame size, shaft, and electrical interface match the 1FK7 Compact family — a direct drop-in for a failed unit already deployed on a SINAMICS S120 drive line.
Spare-part designation with EOL/HOT lifecycle flag
That is exactly the cohort where independent-channel sourcing matters: the manufacturer restricts the part to the spare-part programme rather than full-line production, and lead time/dates are confirmed per RFQ rather than off a stock rotation.
Fit, duty envelope, and what to check before quoting
At 27 Nm and 4.87 kW the motor sits in the mid-power 1FK7 Compact bracket — sized for machine-tool axes, packaging lines, and similar dynamic servo loads where the drive is a SINAMICS S120 in servo control mode with the matching gearbox/coupling on the shaft. Naturally cooled means the 4.87 kW figure is the body-mounted thermal envelope, not a separately fan-cooled rating; if the panel-spec sheet calls for IP-rated or forced-vent duty the derating curve on the motor data sheet governs the real continuous torque, not the headline number. The rotatable plug lets the cable gland be oriented upward, downward, or to either side after mounting — useful when the cabinet layout forces the conduit path to come in from an angle the factory setpoint does not anticipate.
Sourcing posture for the spare-part code
Because the record carries no live price, no live stock line, and no immediate-ship promise, the right move is to drop the BOM line into an RFQ — the spare-part MPN, the lifecycle flag, and the quoted-to-order channel are the three facts the desk needs to come back with availability and current pricing.
