Where this motor drops into the machine
The 1FL2104-4AG00-0MC0: The part is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, sized as a 1 kW / 3.2 Nm axis drive with a rated speed of 3000 rpm — a common rating band for auxiliary axes (conveyor indexers, labelling heads, small gantries, packaging rotary tables) paired with a SINAMICS S200 drive on a 200 V three-phase bus. The matched drive is stated explicitly in the description, so the motor and converter are designed against the same control loop and encoder interface. Mechanically it is a 40 mm shaft-height frame with a plain shaft (tolerance N), a single-cable hybrid connector in the AM2 family, no holding brake, and IP54 with no oil seal. For audit purposes that combination is the lighter-duty option in the 1FL2 line — it is intended for clean, dry inside-cabinet mounting rather than washdown or wet areas, where an IP65/IP67 variant would have to be specified instead.
Rating decoded — what 1 kW at 3.2 Nm really buys
Pn = 1 kW with Nn = 3000 rpm and a stall/continuous torque of 3.2 Nm (M0 = Mn = 3.2 Nm) means the motor delivers rated torque across the full speed range up to base speed without the field-weakening region that higher-speed axes need. In practical terms, the same torque is available at standstill for an indexing move as at 3000 rpm for a continuous conveyor pull, which simplifies sizing for short-duty-cycle loads. As evidenced by the datasheet-style description, the encoder is a 21-bit absolute singleturn device, fed back through the hybrid AM2 connector — that connector carries both the power conductors and the encoder signals on a single cable, reducing panel-side gland count and EMC exposure versus a separate encoder cable run. The protection class is IP54 without an oil seal, so the motor must be mounted where oil mist and coolant splash cannot reach the shaft entry.
Order codes, packaging, and compliance trail
The part is RoHS-compliant since 01-01-2018 and REACH Article 33 information is published, which is the documentation set a municipal or utility tender typically asks for when evaluating a Siemens drive component. No additional UL/IEC third-party certificate is named in the ordering record; if a listing mark is required for the panel, that has to be confirmed against the project specification before release.
Sourcing posture — active line, built to order
The lifecycle field reads current and the brand status is active, fully compliant with the tender-buyer question of whether the part is still being produced. Because the product class is made-to-order, the lead profile is determined by Siemens' build slot rather than shelf stock — the practical procurement path is to quote against the BOM line and confirm the build window at RFQ, not to assume off-the-shelf availability.
