Where the SIMOTICS S-1FL2 1 kW fits in a SINAMICS S200 line
The Siemens 1FL2205-2AF11-1MB0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 product family, sized for the SINAMICS S200 drive platform — a 400 V 3AC supply, rated continuous power Pn of 1 kW at rated speed Nn of 3000 rpm, with a stall torque M0 of 3.6 Nm and continuous torque Mn of 3 Nm at the 48 mm shaft height. It ships with an AM21-bit single-turn absolute encoder on the rear face, a keyed shaft to tolerance N, an integrated holding brake for vertical-axis holding, and an IP65 sealing package with oil seal, so it suits machinery cabinets mounted near the driven load rather than a washdown zone — the connector is a single angular connector rather than a stainless cable gland.
What 1 kW continuous / 3.6 Nm stall means at the driven shaft
A stall torque of 3.6 Nm against a continuous rating of 3 Nm in a 48 mm-frame body gives roughly 20 % torque headroom for accel/decel transients before the drive leaves the continuous operating region — typical sizing territory for conveyors, small indexing tables, and packaging machine axes that cycle inside the S1 continuous envelope. The 400 V 3AC winding pairs directly with a SINAMICS S200 line input rated for that voltage; mounting is the matched SIMOTICS 1FL2 flange pattern at 48 mm shaft height, so the motor is a slot-in replacement within the family — substituting a different frame changes the encoder lamination and the cable exit.
Procurement reality and what ships with the carton
Lifecycle status is current and the export-control class is AL:N / ECCN:N with no license gating for cross-border shipment, so a buyer can quote the line into a multi-national build without export paperwork concerns. The product class is a built-to-order item — single-piece orderable, packaged at 382 x 222 x 240 mm — so it is not a shelf-pull SKU; pricing and lead time are confirmed at quote time against the RFQ quantity. Compliance posture: RoHS conformity since 01-01-18 and REACH Article 33 candidate-list disclosure applies as the standard vendor disclosure for the EU market; no other certifications (UL / CSA / CE) are carried on this product class.
