What this motor is and where it drops in
The Siemens 1FL2102-4AF00-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 product family, built to pair with the SINAMICS S200 drive on a 400 V 3AC supply rail. Continuous output is 100 W at a rated speed of 3000 rpm, with standstill torque and rated torque both listed at 0.32 Nm — a matched figure that suits positioning axes where the load inertia is low and the cycle is short. The motor carries a 20 mm shaft height, an AS17-bit absolute encoder, a plain shaft with tolerance N, and no holding brake, with IP54 protection on the body but no oil seal — so this code is the right pick when the axis can be held by the drive or by an external brake, not the motor itself.
Wiring, connector and commissioning notes
The motor uses a hybrid connector for power and feedback — confirm the cable set matches the SINAMICS S200 drive side before energising, because the S-1FL2 connector family is keyed to its own drive electronics and is not a generic M23/M40 industrial servo plug. At 100 W continuous, this is a low-power positioning axis — typical fits are light-feed applications, small indexing tables, label or print-head drives, and auxiliary axes on a larger machine where a separate small servo is cheaper than scaling up the main drive.
Lifecycle and procurement posture
Product class is C — manufactured to order, not returnable for credit — so the BOM line should be committed with the configured option set (encoder, brake, shaft, sealing) locked in up front; once built, the variant cannot be re-used on a different axis.
Packaging and handling at receipt
The motor ships one per package in a 315 x 182 x 172 mm box — a small, hand-handleable carton sized for a bench receive-and-inspect rather than a forklift unload, so the usual drop-and-check is the full receiving step on this part.
