What this motor is and where it lands in a panel
The Siemens 1FL2204-4AG10-1MC0 is a SIMOTICS S-1FL2 low-inertia servomotor sized for the SINAMICS S200 drive family — 1 kW rated power at 3000 rpm with a 3.2 Nm continuous torque that doubles as the stall torque (M0 = Mn) on a 40 mm shaft height (cite:). That match between rated and stall torque is the headline: it tells you the machine is designed for cyclic point-to-point motion with frequent accel/decel rather than long constant-torque dwells, because there is no torque margin between continuous and zero-speed operation. It ships with a 21-bit absolute encoder, a holding brake, a keyed shaft with N tolerance, and an AM21 hybrid connector for power and feedback in one cable assembly (cite:). That keeps the cabinet-side wiring to a single drag-chain cable per axis — useful when you are running multiple axes into one S200 line-up and want to minimize the cable fill on the cable carrier.
Reading the ratings against the drive pair
Supply is 200 V three-phase and the motor is explicitly matched to the SINAMICS S200 — so the drive-side commissioning file, motor ID, and resolver/encoder parameters are configured for this 1FL2 frame out of the box (cite:, cite:). The IP54 protection class is fine for cabinet-internal or lightly dust-exposed machine interiors but is not a washdown rating; if the motor sits outside an enclosure near coolant or cutting fluid, you need a sealed cover or a different IP rating in the family. The 3.2 Nm at 3000 rpm lands at exactly the 1 kW mechanical output (P = T × ω × 2π/60 ≈ 1005 W), confirming the listed power is the continuous shaft rating rather than a peak — so when sizing the load inertia ratio for a horizontal axis, work from M0/Mn = 3.2 Nm and the drive's current limit, not from a higher transient figure (cite:). The holding brake is the standard fail-safe spring-set type, suitable for vertical-axis static holding; dynamic braking through the drive's brake resistor handles the deceleration energy, not the holding brake.
Compliance and the made-to-order reality
Siemens lists the part as active and current-production, so quoting against the BOM is a normal sourcing exercise rather than a last-time-buy (cite:, cite:). The product is classed as made-to-order (class C): built per configuration, non-returnable — so the order code must be exact before the PO is released, and a cancellation before ship typically does not get a full credit. No UL/CSA/IEC third-party approval is stated on this part's record — the 1FL2 line is designed to meet Siemens' internal product standards and pairs with the SINAMICS S200, but if your panel build carries a third-party listing requirement, that needs to be confirmed against the project spec, not assumed.
Sourcing posture
Group code R220 / product group X0DK (cite:, cite:). Single-piece quantity unit, packed in a 382 × 222 × 240 mm carton (cite:, cite:). Because the part is built to order rather than stocked as a catalog commodity, the right procurement move is to lock the order code into the BOM against the SINAMICS S200 axis configuration and request a quoted lead time and price at RFQ — independent distribution can fill in for short-notice spares or for projects where the factory lead time does not match the install date.
