What this motor is on the line
The Siemens 1FL2204-4AF10-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family designed to run against the SINAMICS S200 drive platform, specified for a 400 V 3AC supply with a rated output of 1 kW at 3000 rpm and a continuous / stall torque of 3.2 Nm on both ratings. The 40 mm shaft height, keyway shaft (tolerance N), integrated holding brake, and IP54 housing without oil seal mark it as a panel-mountable servo designed for machines where the brake must hold a vertical or tilted axis at rest — packaging, small-format pick-and-place, and indexing tables rather than outdoor or washdown duty.
Electrical and mechanical envelope
Equal M0 and Mn at 3.2 Nm tells the integrator the motor has no thermal de-rating gap between standstill and rated speed — a full holding torque at zero rpm means it can spend appreciable dwell time under load without tripping the i²t envelope, which matters for start/stop cycling and clamp-style motion profiles. The 1 kW / 3000 rpm rating against a 400 V 3AC bus maps to the standard European three-phase industrial rail, so the S200 drive pairs from the same supply class without a step-up transformer — cabling is the standard shielded motor lead with the hybrid AS-i style connector terminating into the drive side. The 21-bit absolute encoder and integrated holding brake are wired through the same hybrid connector — the brake lines and feedback share one overmolded plug, so the field-side connector replacement (not the motor swap) covers most disconnect/connector damage events.
Spares handling and shelf posture
The motor ships one per carton at 382 x 222 x 240 mm packaging footprint — physically small enough that two or three units occupy a single shelf bin, but the brake and encoder wiring means a swap-out kit on the MRO shelf should carry the matching hybrid connector kit and the drive-side mating connector, not just the bare motor. Order class is C — built to order with no return credit — so a storeroom carrying this as a critical spare needs to time the reorder against consumption rather than warehousing it as a generic fast mover; a misalignment of two on the shelf is fine, three is a budget conversation.
Lifecycle, compliance, and the sourcing close
Compliance paperwork the buyer will be asked to produce at goods-in is on the standard Siemens product list: RoHS conformity since 01-01-18 and the REACH Article 33 candidate-list statement via the Siemens Reach Information portal; export control classification reads AL:N / ECCN:N, so no special export paperwork attaches to a domestic ship.
