Motor ratings and what they tell the panel builder
The Siemens 1FL2104-2AF10-0SC0 is a SIMOTICS S-1FL2 low-inertia servomotor built to pair with a SINAMICS S200 drive — a 400 V three-phase machine delivering 0.75 kW of rated shaft power at 3000 rpm, with a continuous stall torque and rated torque both rated at 2.4 Nm. Because the M0 and Mn figures match at 2.4 Nm, the motor can hold full torque from standstill to base speed without a torque fold-off zone — a useful property in vertical-axis and constant-tension applications where the load does not back off as the spindle accelerates. The shaft height is 40 mm, the shaft is plain (no keyway) with N tolerance, and the integrated holding brake is factory-fitted — that combination sets the mechanical envelope and dictates the machine-side coupling choice at the bracket.
Encoder feedback and matching drive
Feedback is a 21-bit absolute encoder brought out through the hybrid AS21bit connector — the resolver-style power pins and the data pins live in the same shell, so the cable run to the SINAMICS S200 is a single assembly rather than separate motor-power and signal lines. Mounting follows the SIMOTICS S-1FL2 family footprint at shaft height 40 mm; installation lands inside the standard cabinet envelope for the SINAMICS S200 line, which keeps the panel layout on the documented Siemens template.
Protection class and the deployment envelope
The motor is rated IP54 without an oil seal, putting the body of the machine inside the unsealed cabinet-or-housing envelope rather than wet or washdown zones — a fan-cooled conveyor or assembly-axis inside an enclosure is the working envelope, not a food-and-bev line or outdoor mount. With the holding brake sized for the same 2.4 Nm torque class, it serves the same e-stop and gravity-loaded duty the rest of the SIMOTICS S-1FL2 family is specced for — the brake is present for vertical-axis and rapid-stop holding, not for high-cycle dynamic braking.
Lifecycle status and compliance paperwork
The motor has been RoHS-compliant since 01-01-18 and the manufacturer carries the REACH Article 33 duty to inform on the current candidate list — the SIMOTICS S-1FL2 family is unrestricted for export under ECCN N and AL:N. Packaging is a single-piece shipper at 382 x 222 x 240 mm and the Group Code is R220 within Siemens Product Group X0DK — the same product-class identifier used across the SIMOTICS S-1FL2 ordering structure.
