What this motor is — 1FL2 low-voltage servomotor for S200
The Siemens 1FL2103-4AG11-0MC0 is a member of the SIMOTICS S-1FL2 servomotor family designed to pair with the SINAMICS S200 drive line, with a 200 V 3AC supply, 0.4 kW rated power at 3000 rpm, and standstill torque of 1.27 Nm. The shaft height sits at 30 mm with a plain shaft, tolerance N, and the unit ships with an integrated holding brake. Group Code R220 and Product Group X0DJ place this 1FL2103-4AG11-0MC0 inside the 1FL2 low-inertia family — the compact servomotor class that Siemens positions for smaller CNC axes, packaging machinery, and high-cycle pick-and-place where the S200 drives the commutation. The 1.27 Nm standstill figure means the motor can hold position under load with the brake engaged without saturating the drive's torque limit — relevant for vertical-axis applications where gravity loading is a steady-state concern.
Encoder, brake, and connector — what the -0MC0 suffix commits to
AM21bit encoder feedback is wired through a hybrid connector on the 1FL2103-4AG11-0MC0, single-cable style rather than separate power and signal plugs — that simplifies the panel-side routing and keeps the cable count down on multi-axis machines. Holding brake is fitted, oil-sealed at the shaft exit, and the overall enclosure meets IP65 with the oil seal in place — meaning the 1FL2103-4AG11-0MC0 is sealed against low-pressure water jets and dust ingress, suitable for machine-tools and food-adjacent packaging lines where washdown is intermittent rather than continuous.
Lifecycle status and sourcing posture
Product class is C — manufactured to order, non-returnable, non-reusable against credit. For a procurement line that means the 1FL2103-4AG11-0MC0 is specified into the BOM once and produced to that spec; spares strategy needs to land before the order is released, not after delivery. RoHS compliance is in force since 01-01-18 and REACH Art. 33 disclosure obligation applies per the current SVHC candidate list — the 1FL2103-4AG11-0MC0 ships with the substance-compliance documentation needed for EU-bound machinery builds. No stock count, price figure, or shipment promise is asserted here.
Integration and commissioning notes
Shaft height 30 mm places the 1FL2103-4AG11-0MC0 in the small-frame 1FL2 group — matching gearboxes and planetary reducers from the Siemens product family share this flange footprint, which keeps mechanical integration straightforward on a retrofit where a comparable 30 mm-frame servomotor is being replaced. Because the 1FL2103-4AG11-0MC0 is designed for the SINAMICS S200 only, the commissioning pass is drive-led — the motor is auto-identified once the S200 powers up and the AM21bit encoder handshake completes. No standalone operation; the drive is the controller of record.
