Where this motor drops in
The 1FL2104-2BG01-1MC0: A Siemens SIMOTICS 1FL2 low-inertia servomotor sized for the compact end of the SINAMICS S200 line — 200 V three-phase supply, 0.75 kW rated, 2.4 Nm stall and rated torque, and 3000 rpm rated speed on a 40 mm shaft-height frame. The configuration is explicit on the nameplate: AM21 connector (the hybrid one-cable signal/power plug on this family), single-turn 21-bit encoder, shaft-key mounting with N tolerance, no holding brake, and an oil-seal fitted at the shaft exit for the IP65 enclosure rating.
What the build codes mean
The hybrid connector and single-turn 21-bit feedback pair with the matching SINAMICS S200 drive firmware — substituting a different encoder or a different connector variant from the 1FL2 catalogue is a wiring and parameter mismatch, not a benign drop-in. Without a holding brake, the unit suits axis loads that hold position by counter-torque or external brake — packaging unwind, light conveyors, indexing tables — rather than vertical-axis applications where a power-off brake is the safety requirement. IP65 with the shaft oil-seal rated for the standard shaft-key output means the motor is sealed for splash and dust, but the seal is the wet-end barrier; coolant-jet duty or pressurised washdown beyond IP65 needs a re-specification.
Production status and paperwork
Compliance paperwork is straightforward: RoHS compliance since 01-01-18 and REACH Article 33 disclosure supplied; export classification ECCN N / AL N means no additional licensing paperwork for typical destinations. The product class is 'made to order, non-returnable' (class C) and ships as a single piece per carton — physical dimension 315 × 182 × 172 mm — so a single-unit order arrives in this one carton rather than being split from bulk.
Getting one to a panel
Production-order items with a SINAMICS S200 drive requirement are quoted against the BOM line: motor and drive are commissioned together, and the encoder/connector pairing is fixed by the order code, so confirm the shaft height, brake option, and connector variant against the existing wiring harness before specifying.
