What this 0.75 kW 1FL2 ships with
The Siemens 1FL2304-4AF01-1MB0 is a SIMOTICS S-1FL2 low-inertia servomotor sized for the SINAMICS S200 drive family — 400 V 3AC supply, Pn 0.75 kW, Nn 3000 rpm, with M0 3.02 Nm and Mn 2.39 Nm on the rating plate (cites:,). Built as a 45 mm shaft-height unit with an AM21bit absolute encoder, keyway shaft (tolerance N), angular connector, and no holding brake — IP65 with oil seal at the shaft, so the motor body and seal hold up to washdown environments typical in food-and-bev lines (cites:).
Mechanical options on this build
No holding brake is fitted on the -1MB0 variant — for vertical axes that need a fail-safe hold when the drive is off, a brake option from the same family is the route, but this build runs as a pure dynamic axis (cites:). The AM21bit single-turn absolute encoder on the angular connector gives the SINAMICS S200 absolute position feedback out of the box, so the drive can home on power-up without a separate battery box or incremental reference run (cites:). Packaging is a single-piece carton at 432 × 222 × 240 mm — practical handling for an MRO storeroom: one motor per box, not a multi-pack, so partial pulls don't leave an awkward half-empty shelf (cites:,).
Where this 0.75 kW class actually fits
At 0.75 kW with a 3000 rpm rated speed and 3.02 Nm peak, the 1FL2304 slots into small-format dynamic axes — indexing conveyors, form-fill-seal stations, small pick-and-place, labelling heads, and packaging-servo feeders where a SINAMICS S200 is already on the BOM (cites:,). IP65 with the oil-sealed shaft means the motor can sit near the wet end of a food-and-bev line or a washdown zone, provided the connector face is also mated to a sealed cable gland — the shaft seal is half the rating, the mating half is the other half (cites:).
Lifecycle and the MRO storeroom read
Lifecycle is listed as current and the product is built to order under Siemens group code R220, product group X0DM, product class C — meaning each unit is configured and produced specifically against the order and is not returnable on credit, so the min/max on the shelf has to match real consumption, not a generic reorder trigger (cites:,).
