Matching a 1 kW axis to the SINAMICS S200
The 1FL2104-4BG11-0MC0 is a SIMOTICS S-1FL2 low-voltage servomotor sized at Pn=1 kW with Nn=3000 rpm and matched standstill and rated torque of M0=3.2 Nm / Mn=3.2 Nm — the equal M0 and Mn numbers tell you this frame is not thermally overrated above its continuous rating, so sizing the drive against Mn is safe without a thermal margin penalty. Supply is 200V 3AC and the listed matching drive is the SINAMICS S200, so the motor plugs into the S200 PN servo drive family without an intermediate autotransformer on single-phase-derived 230V shop mains. Encoder feedback is the AM21bit single-turn hybrid resolver-compatible interface and the shaft is plain (no keyway) with tolerance N — important for direct-coupling to a gear or pinion where a key would force an alignment decision at the gearbox input. The holding brake is fitted at the factory, which removes a separate order suffix on the brake variant and lets the S200 drive use the brake release contactor straight from the wiring diagram.
Mechanical envelope and what IP65 with oil seal buys you
Shaft height 40 mm and IP65 protection class with oil seal put this motor on the clean side of a cabinet door or inside a guarded machine envelope, not in a washdown booth — IP65 here is dust-tight and resistant to low-pressure water jets from any direction, with the oil-seal lip added specifically so coolant mist and cutting-oil splash at the shaft exit do not migrate into the bearing housing. For a conveyor, indexing table, or light pick-and-place axis inside a metal-cutting cell this is the right sealing class. The factory carton is a single-piece pack at 382.00 x 222.00 x 240.00 mm — single-quantity packaging, so expect the motor to ship as a one-up box and not a multi-pack tray; lifting and unboxing at receiving should plan for that footprint, especially when the motor is being staged next to an S200 drive on the same delivery.
Ordering codes, compliance, and what ships on the declaration
Export-control classification is AL:N / ECCN:N, which means no export licence is triggered for the common destinations and cross-border shipments do not need an extra filing step beyond the commercial invoice.
Production status and how to pull it onto a BOM
No official successor or cross-reference order code appears in the lifecycle record for this MPN — pair it only with the listed SINAMICS S200 drive family as specified, and keep the encoder (AM21bit) and brake option matched across any replacement motor so the S200 parameter set does not have to be re-cloned.
