Defining the motor on the BOM
Siemens 1FL2103-2AF00-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, built to pair with the SINAMICS S200 drive system — supply voltage 400 V 3AC, rated power 0.2 kW, rated speed 3000 rpm, with stall torque M0 and rated torque Mn both listed at 0.64 Nm. The mechanical package is shaft-height 30 mm with a hybrid AM21 connector (21-bit encoder), shaft key with N tolerance, no holding brake, IP54 protection class without oil seal — a configuration aimed at light, clean-axis motion rather than wet or vertical-load duty.
Sizing the ratings against the load
0.2 kW continuous at 3000 rpm with 0.64 Nm rated torque sets the steady-state envelope for small-format machine axes — light conveyors, indexing tables, small-format packaging and laboratory automation where the dynamic load stays well below 1 Nm peak demand. Because the AM21 hybrid connector carries both power and the 21-bit absolute encoder feedback, the matching drive line is the SINAMICS S200 — pairing it to a different drive family is not a lead-and-plug swap; the encoder protocol and power pinout must match on the drive side. IP54 without an oil seal is fine for cabinet-internal or clean-shop mounting, but it is not a washdown rating — fluid or cutting-oil exposure around the shaft needs an upgraded shaft seal or a higher-IP variant from the same family.
Procurement posture and compliance evidence
Lifecycle status is recorded as active, and the listing carries product class C: built to order, non-returnable — the BOM line cannot be reversed once the unit ships, so spec verification (shaft height, brake presence, encoder type) belongs in the quote review, not after receipt. Compliance records on file show RoHS conformity since 01-01-18 and REACH Art. 33 candidate-list disclosure; export classification is AL:N / ECCN:N, which simplifies cross-border shipment for typical industrial destinations.
Sourcing the order
Built-to-order class and active status point at a quoted-to-order sourcing posture: each line is produced against the order quantity, with availability and pricing confirmed at the time of the RFQ rather than pulled from a standing inventory pool.
