0.75 kW, 3000 rpm, IP65 — what the rating stack actually fixes
The 1FL2304-4AF11-0SB0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 45 mm shaft-height frame, rated Pn = 0.75 kW at Nn = 3000 rpm with a continuous stall torque M0 = 3.02 Nm and rated torque Mn = 2.39 Nm — the gap between M0 and Mn is the overload headroom the drive can pull during acceleration before the torque limit clamps current. The motor is wound for a 400 V 3AC supply, ships with an angular connector outlet, an absolute encoder (AS, 21-bit), a plain shaft to tolerance N, and an integrated holding brake, and is sealed to IP65 with an oil seal so the unit can sit close to a gearbox or in a panel layout where coolant and cutting-fluid splash are routine. It is matched to the SINAMICS S200 drive family, which is the part that defines the bus profile, the safety integration, and the auto-tuning loop — specify the motor and the S200 drive together when filling the BOM line so the encoder scaling and motor parameters are recognised on first power-up.
Lifecycle posture and commercial class
The product class is C — built to order with no return credit — which is standard for configured servo motors and means any RFQ should lock the BOM configuration (brake option, shaft tolerance, encoder type, connector orientation) before the quote is released. Compliance carries RoHS conformity since 01-01-18 and the REACH Art. 33 duty-to-inform disclosure; export control is AL:N / ECCN:N, so the part ships without a special licence hook in the standard jurisdictions.
Commercial metadata for the BOM line
Order quantity is one piece, packaged 432 x 222 x 240 mm per unit, with internal group code R220 and product group X0DM — pass those codes to procurement so the PO matches the manufacturer's order line exactly and the configurator on the vendor portal does not flag the part as mis-ordered.
