What the 1FL2205-4AF11-1HB0 actually delivers on the shaft
The part is a SIMOTICS S-1FL2 low-inertia servo in the 1FL2 family built to pair with SINAMICS S200 drives, sized at 1.5 kW rated power on a 400 V 3AC supply with a rated speed of 3000 rpm, a stall torque M0 of 6 Nm, and a continuous torque Mn of 4.6 Nm on a 48 mm shaft-height frame. The -1HB0 suffix means the motor ships with the holding brake and the oil seal, IP65 protection class on the housing, an AS17-bit absolute encoder on the non-drive end, and a keyed shaft with N tolerance — so the unit is configured for positioning axes that need a positive holding torque at standstill and a sealed cable entry for factory-floor washdown or coolant splash.
Reading the duty numbers against the drive pairing
M0 6 Nm against Mn 4.6 Nm gives roughly 1.3× short-term overload headroom above continuous — that is the envelope the S200 drive exploits during acceleration ramps, and it is the figure that decides whether the motor can hold a peak load cycle without tripping the drive's I²t model.
Compliance and what ships in the box
Siemens marks the part RoHS-compliant since 01-01-18 and carries the REACH Art. 33 duty-to-inform disclosure; export-control classification shows AL:N / ECCN:N, so the motor is not subject to the dual-use paperwork that sometimes delays other Siemens motion SKUs across the border. Order quantity is one piece per shipper, packaged at 382 × 222 × 240 mm; the product class flag indicates built-to-order, which is the standard posture for 1FL2 configurated SKUs rather than shelf-stock spares.
