1FK2104-5AK11-0SA0 — what the motor actually delivers on the shaft
Siemens SIMOTICS S-1FK2 HD servo motor from the 1FK2 servomotors family, sized for SINAMICS S210 drive pairing, with stall torque M0=2.4 Nm and rated power PN=1.07 kW at nN=6000 rpm on a 380-480 V bus, and PN=0.75 kW at nN=3000 rpm on a 200-240 V bus. The 380-480 V / 200-240 V pairing means the same frame is shipped into both 230 V-class and 400 V-class cabinets without a winding change, which keeps the spare on the MRO shelf flexible across line voltages. Holding brake is fitted, IP65 housing, cylindrical shaft D19x40 mm, AS22DQC single-turn 22-bit absolute encoder, and an M17 rotatable plug with OCC interface — so commissioning day is plug-in, set the encoder in the S210 project, and run. No laptop archaeology required at startup: the S210 auto-identifies the motor through the OCC interface and the resolver/encoder pairing is pre-validated.
Ratings that drive the BOM decision
The 1.07 kW / 6000 rpm / 2.4 Nm combination places this motor in the compact high-dynamic class for the 1FK2 family — the M0 stall figure is what you derate against for vertical-axis holding, the PN figure is the continuous shaft power available at rated speed, and the dual voltage window (380-480 V vs 200-240 V) is what makes the same order code usable on both 230 V and 400 V line cabinets without a re-spec. The holding brake is sized to hold the rotor at standstill with the rated load, so vertical-axis drops on power loss are held without an external mechanical brake. IP65 sealing covers the dust and low-pressure water-jet duty — fine for cabinet-side mounting and washdown-adjacent zones, but not submersion or high-pressure cleaning. The D19x40 mm cylindrical shaft is the standard keyed mounting interface for this frame, so the coupling and pinion selection is a stock catalogue exercise rather than a custom machining job.
Compliance, packaging, and what arrives on the dock
RoHS compliance since 01-07-06, REACH Article 33 information available on the candidate-list portal, and export-control classification AL:N / ECCN:N_CNDU — i.e. no special export licence is triggered for standard commercial shipments. The packaging dimensions 452.00 x 250.00 x 267.00 mm confirm a single-motor pack; product class is C (made-to-order, non-returnable), which is normal for configured servo motors and worth flagging internally before a unit is pulled off the shelf and returned unused.
