What this motor is and where it sits
The 1FL2102-2AG10-0MC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, built to drive on a 200 V 3AC supply with a rated power of 50 W and a rated speed of 3000 rpm, delivering 0.16 Nm continuous torque at standstill (M0) and at rated load (Mn). The shaft height is 20 mm, the shaft is a plain cylindrical type with tolerance N, and the body carries an IP54 protection rating without an oil seal, making it suitable for clean industrial enclosures but not for direct washdown exposure. A holding brake is fitted, and the feedback is a 21-bit absolute multi-turn encoder resolved through the AM21 hybrid connector — meaning the drive electronics receive absolute position on power-up and the brake holds the axis when the servo stage is de-energised, so no homing move is required after a controlled stop. This part is sized as the SINAMICS S200's smallest companion: a 50 W servomotor matched to that drive family's compact control cabinet, where short wiring runs and tight panel space call for a low-inertia rotor rather than the higher-inertia frames used in larger machine axes.
Ratings in plain terms — what 0.16 Nm and 3000 rpm mean at the shaft
A 0.16 Nm continuous figure paired with 3000 rpm corresponds to 50 W of mechanical shaft power — the headroom for accelerating small-format load inertias such as indexing tables, lab automation axes, light-duty labelling heads, or pick-and-place subassemblies where cycle time matters more than raw holding torque. Because the rotor is a low-inertia design (the 1FL2 family targets high dynamic response), the motor accelerates faster than a comparable high-inertia frame at the same torque — useful for short-stroke point-to-point moves, less useful where the load inertia dominates and the motor is asked to drive it from a standstill for long periods.
Holding brake, feedback, and panel-side wiring
The integrated holding brake is engaged when the servo stage is off, holding the axis in position under no power — a requirement for vertical or gravity-loaded axes so the load does not free-fall on a stop event. The 21-bit absolute encoder over the AM21 hybrid connector returns absolute position without a homing reference after power-on, which removes the routine homing step at every machine restart. The 20 mm shaft height and plain shaft with tolerance N are sized for direct coupling to a small gearbox or for pulley/belt transmission in compact machine modules; the IP54 rating without oil seal fits dry industrial environments, and should not be specified where oil mist or washdown is present.
Build-to-order product class and lifecycle
Siemens classifies this motor under product class C — produced to order, not reusable or returnable against credit — meaning each unit is built against a specific order rather than drawn from a finished-goods pool, and lead time is governed by the order book on the production line. Lifecycle status is current, and the part carries Group Code R220 within Product Group X0DJ; RoHS compliance is documented from 01-01-18 and REACH Art. 33 information is provided per the current candidate list, while the export-control designation is AL:N / ECCN:N — i.e. no special export licence is required for shipment to most destinations.
Sourcing posture for the BOM line
Because the unit is produced to order under product class C, the part is quoted against the BOM quantity rather than pulled from shelf stock; lead time and price-break ladder are confirmed at RFQ, and an expedite path is typically available against the production slot for line-down situations.
