Definition and ratings
Siemens 1FL2104-4BF01-0SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, sized for the SINAMICS S200 drive platform. The supply is 400 V three-phase AC, with rated power 1 kW and rated speed 3000 rpm; both standstill torque M0 and rated torque Mn are 3.2 Nm, so the motor delivers its full torque envelope at zero speed as well as at base speed. The mechanical package is a 40 mm shaft height with a plain shaft, tolerance N, and no holding brake; the feedback is a 21-bit absolute encoder and the connection is a hybrid cable connector. Protection class IP65 with oil seal suits installations where coolant mist or lubricant splash reaches the motor face — the sealing is on the shaft entry, not the housing thread, so the rating holds under continuous wet-side exposure typical of machine-tool and packaging environments.
Drive pairing and electrical fit
The matching drive on the manufacturer record is SINAMICS S200, so the cable set, encoder protocol and parameter set are pre-validated against that controller. With 1 kW at 400 V 3AC the motor sits in the lower end of the S200 power range, which is the right slot for indexing tables, small gantries, label and label-feed axes, and auxiliary infeed rollers where a 3.2 Nm continuous torque and 3000 rpm ceiling cover the motion envelope without oversizing the drive. Because M0 equals Mn at 3.2 Nm, the constant-torque region runs from standstill up to base speed, which matters for start-stop profiles and holding loads under torque demand without field weakening — pick this frame when the duty cycle dwells at low rpm rather than spinning at high speed.
Lifecycle and BOM sourcing
Lifecycle stage is recorded as current and the product is active. Product class is built-to-order: the motor is produced to order and is non-returnable, so the BOM quantity should be sized to the actual build rather than padded as buffer stock. RoHS compliance is in force since 01-01-18 and REACH Art. 33 candidate-list information is published, so the EU compliance file for the cabinet can reference the manufacturer record without a separate substance declaration. Export control is unrestricted: AL:N / ECCN:N.
Catalog identifiers and shipping
Group Code R220 and Product Group X0DK are the manufacturer-side identifiers used on the packing list and the PO line; both should match the order acknowledgment to confirm the right variant is on the build sheet. The unit ships one per carton with packaging dimensions 315.00 x 182.00 x 172.00 mm — relevant when pre-sizing the goods-in bay for a batch receipt.
