What the 1FL2105-2AF11-1HB0 actually is on the bench
The 1FL2105-2AF11-1HB0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, sized for a 400 V 3AC supply and matched to the SINAMICS S200 drive line. Shaft height 52 mm and a frame built around Pn = 1.5 kW at Nn = 3000 rpm make it the mid-frame motor in the S-1FL2 set, suited to packaging, small-format handling and light feed-axis duty where a 1FL2 partner drive is already specified.
Ratings — what 1.5 kW and 4.6 Nm mean for the BOM
Continuous rated power Pn = 1.5 kW at Nn = 3000 rpm with Mn = 4.6 Nm continuous and M0 = 5 Nm stall defines the working envelope. The stall/continuous torque spread is narrow, so the motor delivers near-rated torque across the speed range rather than only at zero speed — relevant when the axis needs high dynamic torque during accel, not just at hold. Feedback is the absolute encoder AS17 bit single-turn, wired through an angular connector with a keyed shaft. The holding brake is integral, which removes a panel-side brake chopper wiring step on vertical axes and tightens the E-stop stop-distance budget on a gravity-loaded slide.
Mounting, sealing and cabinet-side integration
IP65 with oil seal on the shaft end rates the housing for splash and light coolant exposure, but the rating is achieved with the seal seated at the shaft — a dry-running or abrasive-dust install will shorten seal life and is outside the sealed envelope. The motor bolts down through the standard 1FL2 foot pattern on shaft height 52 mm, and the angular connector rotates to a service-friendly orientation before the bolts are torqued. Shipped individually with packaging dimensions 432 x 222 x 240 mm, the unit rides a one-piece pack rather than a multi-up tray. Drop-in replacement on a line means one spare on the shelf, not a kit of ten, so a critical-spare holding philosophy treats each motor as a single-quantity BOM line.
Compliance documentation on record
RoHS compliance has been declared since 01-01-18 and REACH Art. 33 candidate-list information is published, which is the documentation trail an inbound-goods inspection will check against the PO. Export control markings AL:N / ECCN:N mean no licence trigger under the default classifications for routine cross-border shipment.
