What this motor ships as on the BOM line
The Siemens 1FL2204-4AG01-0HC0 is a SIMOTICS S-1FL2 low-voltage servo in the 1FL2 family, scaled for the SINAMICS S200 drive platform. Continuous rated power is 1 kW at 3000 rpm with a 3.2 Nm continuous torque equal to the stall torque, so the motor delivers its rated torque across the constant-torque region up to base speed without an early torque fold-back (cites:). The mechanical package is a 40 mm shaft-height frame with a plain shaft (tolerance N), no holding brake, and IP65 protection with an oil seal at the shaft pass-through — the seal choice makes this the build to specify for gear-driven axis ends where lubricant splash reaches the shaft, not for purely dry cabinet-side mounts (cites:).
Commutation, feedback, and the drive it pairs with
Commutation is closed-loop through a 17-bit single-turn absolute encoder on a hybrid connector — the absolute feedback preserves axis position through power cycles, which matters for indexing axes and vertical loads where re-homing on every restart would steal cycle budget. The windings are supplied from a 200 V 3AC bus, matching the SINAMICS S200 input class (cites:). Without a holding brake fitted, the motor holds position only through the drive's closed-loop torque control; vertical or gravity-loaded axes using this build need a mechanical brake or a separate holding arrangement downstream of the gearbox. The lack of a brake here also keeps the rotor inertia lower, which helps when the cell budget is tight on accel/decel time (cites:).
Lifecycle state, compliance, and order codes on the data sheet
Lifecycle is recorded as current, and the product class is built-to-order — each unit is produced against a specific order and is not returnable against credit, so the line that commits this motor is committing to a non-cancellable build slot. Group Code R220 and Product Group X0DK are the catalog identifiers a planner will see on the Siemens price list and on the MRO purchasing screens (cites:,). Compliance posture is documented for RoHS since 01-01-18 and carries the REACH Article 33 duty-to-inform flag — the declaration pack carries the candidate-list substance status at the time of shipment. Export control is AL:N / ECCN:N, which means no special export licence footprint in the major industrial regions (cites:,).
Sizing the line and the buying channel
For cell sizing: 1 kW continuous at 3.2 Nm and 3000 rpm lets an integrator budget roughly the 3.2 Nm torque envelope through the rated speed, with peak acceleration set by the drive's current limit rather than the motor's continuous rating. The 40 mm shaft height and IP65 oil-seal spec tell the panel layout the motor bolts to a small-flange face — confirm the matching SINAMICS S200 line filter and motor cable before freezing the BOM (cites:). As a built-to-order Siemens servo with current lifecycle status, this motor is sourced through Siemens-authorized distribution against a confirmed order — pricing and lead time are quoted per RFQ against the BOM quantity, not held as shelf stock (cites:,).
