400 V 3AC, 1 kW, 3.2 Nm — sized for the SINAMICS S200 line
The Siemens 1FL2104-4BF11-1MC0 is a member of the SIMOTICS S-1FL2 low-inertia servomotor family, built for direct pairing with the SINAMICS S200 drive platform (cite:, cite:). It runs on a 400 V 3AC supply rail, delivers 1 kW continuous (Pn) at 3000 rpm (Nn), and holds a stall and rated torque of 3.2 Nm (M0 = Mn) — a matched motor/drive combination where the controller, power stage, and feedback are designed as one system (cite:).
Shaft, brake, and feedback — what lands on the machine
The mechanical face is a shaft-height 40 mm frame with a keyed shaft (tolerance N) and an integrated holding brake, terminated through a hybrid AM21bit encoder connector — the single-cable hybrid link keeps the brake power and absolute encoder feedback on one connector, simplifying cabinet routing versus dual-cable servos (cite:). The housing carries IP65 with an oil seal, so the motor takes the washdown and light coolant exposure common around packaging, light-conveyor, and small-format machine tools — the seal rating is at the shaft exit, not the connector face (cite:).
Class C, made-to-order — what that means for the BOM line
The product is classified Group Code R220, Product Group X0DK, and carries product class C — built to order, non-returnable, non-reusable for credit (cite:, cite:, cite:). Lifecycle status is active (cite:, cite:), so production is open and the order code is current; lead time and quantity pricing are confirmed at quote rather than off shelf stock.
Compliance and shipping footprint
RoHS compliance has been in force since 01-01-18, with REACH Article 33 candidate-list information available on request, and the part carries AL:N / ECCN:N for export — no special license routing required for standard commercial shipments (cite:, cite:, cite:). The unit ships as one piece in a 382 x 222 x 240 mm pack (cite:).
