1.07 kW at 6000 rpm — sized for what load profile
The 1FK2104-5AK00-0MB0: The part is a SIMOTICS S-1FK2 HD servo motor in the 1FK2 family, built to mate with SINAMICS S120 drive line-ups through a DRIVE-CLiQ plug. Stall torque is 2.4 Nm with a rated power point of 1.07 kW at nN=6000 rpm on a 380-480 V bus and a second rated point of 0.75 kW at nN=3000 rpm on 200-240 V — so the same winding can be commissioned on either a 230 V class or 400 V class SINAMICS S120 infeed without rewiring the motor side. The M0=2.4 Nm figure is the deciding parameter for sizing the load — at 6000 rpm with a 2.4 Nm ceiling the continuous shaft power is fixed by physics, and any short-duration torque demand above that constant requires the drive's peak-current headroom, not a different motor.
Shaft, feedback, sealing — what the M17 connectors tell you
The shaft is a cylindrical D19 x 40 mm — the 19 mm journal and 40 mm length set the coupling selection and the axial foot-load budget; a helical-beam or jaw-type coupling in the 19 mm bore family is the usual mating choice. Feedback is the AM22DQC absolute encoder, 22-bit single-turn plus 12-bit multiturn — meaning the drive powers up with absolute shaft position retained across power cycles, no homing routine required on every restart. DRIVE-CLiQ on the M17 plug carries the encoder data and the electronic nameplate to the SINAMICS S120 in one cable, and the M17 power connector carries the motor windings — both are the family-standard connectors for the 1FK2 generation, so a spare pre-made cable from another 1FK2 in the plant drops in. IP64 sealing on the housing body, with the connector face sealed at the mated plug — fine for typical industrial cabinet-internal or sheltered machine mounting; not rated for direct washdown exposure.
Active in production — how to land it on a live BOM line
Lifecycle is recorded as current on the Siemens catalog record, with product status Active — meaning the order code remains a live factory orderable against a SINAMICS S120 configuration. Product class is C: items manufactured to order, which cannot be reused or re-credited — so a cancelled or wrong-configured unit is non-returnable, and the BOM line should be frozen before the RFQ is released rather than padded with safety stock that cannot come back. Export classification is AL:N / ECCN:N_CNDU, which simplifies cross-border shipments — no export license paperwork needed for typical industrial destinations.
Storeroom view — group code R220, product group 9021
The internal Siemens Group Code is R220 and the Product Group is 9021 — these are the catalog hooks the storeroom uses to bin the part alongside other 1FK2 / SINAMICS S120 family items, not buyer-facing order specs. Single-piece packaging at 452 x 250 x 267 mm — the carton footprint, not the motor, is what dictates the receiving-bench space and the inbound inspection cradle dimensions when one arrives from the factory.
