1.07 kW at 6000 rpm, 2.4 Nm stall, holding brake engaged
The 1FK2104-5AK10-2MA0 is a SIMOTICS S-1FK2 HD servomotor sized at M0 = 2.4 Nm with PN = 1.07 kW at nN = 6000 rpm on a 380-480 V bus and PN = 0.75 kW at nN = 3000 rpm on a 200-240 V bus, sold as part of the 1FK2 family that pairs directly with the SINAMICS S210 drive. Holding brake is integrated into the frame, the shaft is a cylindrical D14 x 30 mm profile, and feedback is a 22-bit single-turn plus 12-bit multiturn absolute encoder (AM22DQC) over the OCC interface — the resolution a high-dynamic feed axis needs to hold sub-arcsecond following error through the servo loop. Degree of protection IP64 on the housing with a rotatable M17 plug at the connection end, so the cable exit can be clocked to the cabinet layout without spinning the motor body in the bracket.
Two voltage bands, one frame — what the BOM must fix
The rated power shifts with the bus: 1.07 kW at nN = 6000 rpm on 380-480 V, and 0.75 kW at nN = 3000 rpm on 200-240 V — sizing the upstream SINAMICS S210 line module and the cabinet transformer tap against the higher of the two ratings if the line runs across both voltage classes. Product Group 9021 / Group Code R220 places this SKU in the standard Siemens configurator hierarchy, and the lifecycle field reads current — orderable against the BOM without an LTB window on the record.
Compliance posture and logistics envelope
RoHS substance restrictions have been declared since 01-07-06 and the line carries the current REACH Art. 33 candidate-list information set; export control is AL: N / ECCN: N_CNDU, so cross-border shipments do not require a separate export licence under the cited classification. Quantities ship as 1 Piece per unit, packaged at 452.00 x 250.00 x 267.00 mm, and the product class is C — built to order, non-returnable, non-reusable for credit — so a partial-quantity MRO spare on this code needs to match the build slot rather than ride a stock shelf.
Sourcing posture for an active, built-to-order servomotor
Quoted to order against the configured BOM line through independent industrial distribution; availability, current pricing, and the build lead time are confirmed at RFQ — no ex-shelf promise, no OEM-direct dispatch claim.
