100 W shaft output on a 20 mm-frame SIMOTICS
The Siemens 1FL2102-4AF01-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, sized for SINAMICS S200 drives — a 100 W continuous rating at 400 V 3AC supply, 3000 rpm rated speed, with stall and rated torque both at 0.32 Nm on a 20 mm shaft-height frame (cite:). The 100 W point sits at the small end of the SINAMICS S200 servo range, so the 0.32 Nm continuous figure is the load ceiling the drive must command — not the peak torque the servo can briefly deliver. For a buyer, the 0.32 Nm / 3000 rpm figure translates to roughly 100 W of mechanical shaft output under continuous duty, which maps to small-format motion: indexing tables, light conveyor transfers, lab-automation axes, and end-effectors on pick-and-place heads. The 20 mm shaft height keeps the motor footprint compact for tight machine builders, and the hybrid (AM21bit) encoder feedback closes the position loop on the SINAMICS S200 without a separate resolver cable run.
Mechanical and environmental envelope
Mechanical options on this build: keyed shaft (tolerance N) and no holding brake — meaning the load must be held by the drive's vertical-axis counterbalance, a mechanical brake on the gearbox, or the application itself; the motor does not contribute a failsafe hold (cite:). The IP65 rating with oil seal covers dust and jetting water at the shaft exit, suitable for machine interiors with coolant splash and food-and-beverage peripheral zones, but it is not a washdown-rated food-zone or outdoor-exposed seal. Shaft height 20 mm places the motor in the S200 compact frame set, where the matching drive electronics assume the short cable run from converter to motor — long motor-lead extensions would push the 400 V 3AC PWM edges past the cable's allowable dv/dt and risk shaft-bearing currents on this oil-sealed assembly.
Compliance and order data
Production status is recorded as active under lifecycle stage current, with a Group Code of R220 and Product Group X0DJ on the Siemens ordering system, and the product is classed as C — manufactured to order, not returnable for credit, so the RFQ has to call out the build quantity up front (cite:,). Packaging is one piece per shipper, in a 315 x 182 x 172 mm box, so multi-unit orders box individually rather than as a multi-pack (cite:,). Substance-compliance position: RoHS conformity since 01-01-18, with REACH Article 33 candidate-list information carried by Siemens under the standard Reach Information disclosure (cite:,). Export control shows AL:N / ECCN:N, meaning no specific export licence flag applies under the default classification on the ordering data (cite:).
Panel-side integration checklist
Pair this motor only against the SINAMICS S200 drive family from the 1FL2 servo line — the encoder protocol (AM21bit hybrid single-cable) and the 400 V 3AC power stage are matched to that converter set. Mounting on the machine face uses the standard 20 mm-flange bolt circle; align the shaft key to the coupling hub before torquing the bolts to avoid a radial load on the oil seal during commissioning. With no holding brake in this build, the safety stop on a vertical axis needs an external mechanical brake sized for 0.32 Nm continuous plus the application's worst-case load — do not let the servo zero-speed torque carry the safety function. Cable routing matters: the hybrid (AM21bit) connector carries both power and feedback in one cable, so specify the matching Siemens hybrid lead and respect its minimum bend radius. Conduit entries into the cabinet should land near the SINAMICS S200 terminal block to keep the motor lead short — this 100 W compact frame does not tolerate the same lead lengths the larger 1FL2 shafts do.
Sourcing posture
Class-C build-to-order structure means the motor is built against the purchase order, not pulled from a finished-goods floor — for the buyer's BOM this translates to a quoted lead time against the build schedule rather than a stock-on-shelf read. No AVL pinch point is recorded here: the brand is Siemens, the family is 1FL2 for SINAMICS S200, and the order code partitions cleanly by shaft height, encoder and brake option. For a contract-manufacturing line where the end-client has Siemens on the approved-vendor list, the 1FL2 series sits on that AML by default. A deviation request would only be needed if the build called for a non-Siemens servo into a Siemens-only panel — which is not the case here. Always cross-check the AM21bit hybrid-encoder option and the no-brake / keyed-shaft selections before submit, because those two mechanical codes are the ones that decide whether a drop-in works on an existing axis.
