What this motor is and what it pairs with
The 1FL2104-2BG01-0SC0 is a Siemens SIMOTICS S-1FL2 low-inertia servomotor in the 40 mm shaft-height frame, rated 0.75 kW continuous at 3000 rpm with 2.4 Nm standstill and rated torque, and wired through a hybrid AS21bit absolute encoder connector. It is built to drop into a SINAMICS S200 drive line-up — the motor and drive are specified as a matched pair, so commissioning is a same-platform pairing rather than a cross-vendor integration.
Ratings that decide the fit
Continuous output is 0.75 kW at a rated speed of 3000 rpm, with 2.4 Nm standstill torque and 2.4 Nm rated torque — the equal standstill/rated figure tells you there is no extended constant-power plateau at the top of the speed range, so for high-speed machining spindles above base speed the torque will taper quickly. Supply is 200 V three-phase; the motor carries an IP65 seal with oil-resistant sealing for the shaft exit, which means coolant, cutting fluid and light oil mist around a machine-tool axis are inside the rated envelope rather than outside it. Feedback is AS21bit absolute — a single-turn/multi-turn absolute encoder that holds position through power cycles, so the axis does not need a home-return routine after every E-stop or mains dip. The shaft is plain, tolerance class N, with no holding brake fitted — no brake means the motor holds position only while the drive is actively torque-controlled, which rules out vertical-axis use without an external mechanical brake on the gearbox or ballscrew.
Lifecycle, ordering class and compliance
Group Code R220 and Product Group X0DK are the internal commercial identifiers a buyer will see on the Siemens price list and order acknowledgement — useful when reconciling the order code against the PO line. Compliance footprint on file: RoHS-conformant since 01-01-18, REACH Article 33 duty-to-inform per the current candidate list, and export classification AL:N / ECCN:N — no export licence trigger for standard cross-border shipment.
Procurement angle
For a machine builder sizing a SINAMICS S200 axis, this is the 0.75 kW / 40 mm-frame companion motor — specified alongside the matching S200 drive module in the same BOM line. Independent distribution carries it against an RFQ: pricing and lead time are confirmed at quote time on the production quantity, with manufacturer traceability preserved. No direct stock figure or next-day shipment promise is published — the made-to-order class means lead time is production-bound, not shelf-bound.
