0.4 kW at 3000 rpm in a 30 mm stack — what fits where
The Siemens 1FL2103-4AG00-1MC0 is a SIMOTICS S-1FL2 servomotor rated 0.4 kW from a 200 V three-phase supply, delivering 1.27 Nm of both rated and stall torque at 3000 rpm with a 30 mm shaft height — a footprint that drops into compact machine axes where cabinet space and rotor inertia both matter. It is a Class C product — made to order, not reusable or returnable for credit — so the BOM line locks once it is placed and any spares carry a real holding cost on the shelf.
Shaft, feedback, brake — the few switches buyers actually debate
Feedback is a 21-bit encoder on a hybrid AM21 connector — that connector/cable choice is paired with the SINAMICS S200 drive the motor is matched to, so the field-side cable and the drive-side connector slot are tied to the same S200 system. The shaft is keyed to tolerance N and supplied without a holding brake, which means the application has to handle the gravity-load hold electrically through the S200 or accept back-drive on E-stop — a relevant check before quoting against a vertical-axis machine. IP54 with no oil seal suits general factory atmospheres; it is not a washdown or food-grade rating, so the deployment ceiling is dry machine cells, not wet zones.
Procurement-level codes and shelf footprint
Group Code R220 and Product Group X0DJ are the internal classification pair a buyer or MRP controller will see on the line — both come back the same on every order, which keeps the BOM record clean across vendors. Each unit ships as one piece in a 315 x 182 x 172 mm pack, which is the slot to budget in a small-parts bin; one motor per inner pack, no inner-pack sub-multiple for split orders.
Lifecycle and compliance for the MRO buyer
Export Control shows AL:N and ECCN:N, meaning the part is not license-triggered for typical export filings — a small but real relief for sites shipping assembled product to multiple regions.
