1 kW / 3.2 Nm on a 40 mm flange — sized for S200
The Siemens 1FL2104-4BG01-0MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, rated 1 kW continuous with a 3.2 Nm standstill and 3.2 Nm rated torque at 3000 rpm from a 200 V 3AC supply — the headline numbers that decide whether it covers the axis or stalls under the load. Shaft height 40 mm with a plain shaft, tolerance N, and a hybrid AM21bit connector plus 21-bit single-turn absolute encoder — the package that drops straight onto a SINAMICS S200 drive without adapter plates or third-party cable assemblies. Built without a holding brake and sealed to IP65 with oil seal, so it suits vertical axes that already have a mechanical brake or gravity-safe load, and any mounting where cutting fluid or gear lube mist reaches the shaft exit.
Why this lands on an S200 and not somewhere else
Siemens lists the matching drive as SINAMICS S200, so the motor cable, encoder feedback, and electronic nameplate are keyed to that drive — the 1FL2104-4BG01-0MC0 will auto-identify on the S200 bus without manual parameter entry. Group Code R220 and Product Group X0DK are the internal Siemens order-classification tags used for purchasing and routing inside the S200/1FL2 line — they confirm the motor sits in the standard S-1FL2 ordering structure rather than a legacy or third-party catalogue path.
Compliance and order-class posture
RoHS compliance since 01-01-18 and REACH Art. 33 duty-to-inform apply, with current candidate-list data referenced — the standard EU substance-restriction posture for a current-production Siemens drive accessory. Export-control status is AL:N / ECCN:N, so the part ships without a licence trigger to most destinations, and Product class C means each unit is built to order — no re-use, no return-for-credit, every motor goes through a fresh production slot.
