What the 1FL2102-2AF10-1MC0 actually delivers
The 1FL2102-2AF10-1MC0 is a low-inertia SIMOTICS S-1FL2 servomotor in the 1FL2 family, built to run on a 400 V 3AC supply alongside the SINAMICS S200 drive. Continuous power sits at 50 W with a rated speed of 3000 rpm, and both the stall torque Mn and continuous torque M0 come in at 0.16 Nm, which is the figure you use when sizing the acceleration window for a small pick-and-place or indexing axis. Mechanical interface is shaft height 20 mm with a keyed shaft to tolerance N, and the motor carries a holding brake so a vertical or back-driven axis holds position when the drive is de-energised. Feedback is a 21-bit absolute encoder on a hybrid (AM21) connector, and the body is sealed to IP54 without an oil seal — fine for cabinet interiors and clean factory air, not for washdown or wet duty. The motor is produced to order (product class C), not pulled from a stocked shelf. Lifecycle is current and the part is not flagged for discontinuation, so the BOM line is safe for ongoing panel builds and planned spares.
Drive pairing and control-loop fit
The 1FL2102 is the motor half of a matched pair with the SINAMICS S200 — the drive is sized for the 1FL2 low-voltage family, so auto-tuning, encoder initialisation, and the brake control sequence are all pre-mapped. With a 21-bit absolute encoder in the loop the velocity and current loops have the resolution needed for tight positioning without crawl, which matters on a 50 W axis where the mechanical inertia is low and any dead-band shows up as jitter at standstill. Group code R220 and product group X0DJ are the internal Siemens classification rows used by procurement and Spares for cross-referencing the part within the 1FL2 line. They do not affect electrical fit but they do drive how the part appears in the Siemens configurator and in stock-class reports.
Compliance paperwork for the declaration pack
Export control classifies the part as AL:N / ECCN:N, so it ships without an export licence gate in the usual jurisdictions.
Sourcing posture for this build-to-order motor
The 1FL2102-2AF10-1MC0 is built to order against the BOM — class C in Siemens terms — so availability is not a stocked-shelf question. It is quoted per RFQ against the build quantity and the configured options, with current pricing and lead time confirmed when the order line is opened.
