What this motor is, in plain terms
The 1FL2102-4AF01-0SC0 is a SIMOTICS S-1FL2 low-inertia synchronous servo in the 1FL2 family, rated for 400 V three-phase supply with a rated power Pn of 100 W and a rated speed Nn of 3000 rpm, so it sits at the small-frame end of the SINAMICS S200 servomotor line where torque density and short-axis footprint matter more than raw output power. Both standstill torque M0 and rated torque Mn are listed at 0.32 Nm, which means the motor delivers the same torque at zero speed as at rated speed — a useful profile for indexing tables and small-format pick-and-place axes where holding load at standstill is part of the duty cycle. Feedback is absolute single-turn 21-bit (AS21bit) over the hybrid cable, so position is retained on power-up without a homing routine — integrator-relevant for any axis that must start from a known angle after a power loss.
Fit, shaft, and sealing details that decide the swap
Shaft height is 20 mm with a plain shaft, tolerance N, and no holding brake — the absence of a brake is load-bearing for selection: this motor will not hold a vertical axis on power loss, so the application has to be a horizontal drive or one with a separate mechanical brake on the gear train. Protection class is IP65 with an oil seal, so the motor body resists low-pressure water jets and light oil contamination but is not rated for washdown immersion — panel-side mounting next to a gearbox or ball-screw is the typical application envelope.
Production status, lifecycle, and compliance paperwork
Product class is recorded as 'manufactured / produced to order' with return-for-credit disabled — buyers should treat each unit as a build-to-order item rather than a stocked, returnable catalogue line, and plan delivery windows around the RFQ confirmation rather than off-the-shelf expectations. Substance-compliance paperwork is available: RoHS conformity is declared since 01-01-18, and REACH Article 33 candidate-list information is published by Siemens. Export-control classification is AL:N / ECCN:N, so the part is not licence-restricted for the standard export destinations. Internal classification carries Group Code R220 and Product Group X0DJ — relevant for buyers reconciling a Siemens PO line or audit trail against the supplier's own group-code schema, not a functional selection parameter.
Sourcing posture for an active servo motor
Supplied against an RFQ: confirmed-active Siemens SIMOTICS 1FL2 small-frame servos are quoted to order for the requested quantity, with pricing and availability returned at quote time rather than off a live shelf. Each piece ships individually in a 315 x 182 x 172 mm carton (1-piece pack) and is not returnable against credit under product class C, so spares planning should size the on-hand quantity against real service intervals instead of relying on return-window hedging.
