What the motor gives you on the line
The Siemens 1FL2103-2AF01-0MC0 is a SIMOTICS S-1FL2 low-inertia servomotor sized for 0.2 kW continuous output on a 400 V 3AC supply, with a rated speed of 3000 rpm and 0.64 Nm standstill/rated torque — the right envelope for small-format positioning axes, indexing tables, and lab/bench automation where a compact, repeatable servo is needed. It belongs to the 1FL2 family designed to pair with the SINAMICS S200 drive — the motor and drive are matched as a system, so the encoder protocol, power lead, and commissioning parameters line up without cross-vendor tweaking.
Mechanical and electrical build
Shaft height 30 mm with a plain shaft to tolerance N and no holding brake — this is the motor to pick when the load is held in position by a separate brake, a counterweight, or the downstream mechanism, not the motor itself. The hybrid connector AM21bit on the drive-end carries power and the 21-bit absolute encoder feedback in one cable assembly — single-cable routing simplifies the panel gland and the moving cable carrier on short-stroke axes. IP65 protection class with an oil seal means the motor housing withstands light coolant spray and oil mist typical of a machining cell or a washdown-adjacent station, but it is not rated for full submersion or high-pressure hot washdown.
Built-to-order line and compliance footprint
The part carries product class C — manufactured to order, non-returnable for credit — which is the normal posture for a configured Siemens servo line and means planning the build into the BOM rather than treating it as off-the-shelf stock. Compliance with RoHS substance restrictions has been declared since 01-01-18 and the REACH Art. 33 duty-to-inform applies per the current candidate list — the documentation pack travels with the line in the usual Siemens format.
How it shows up at the receiving dock
Each unit ships as a single piece in a 315.00 x 182.00 x 172.00 mm pack — useful to know when planning inbound bench space and unboxing for a drive commissioning session. The line carries group code R220 under product group X0DJ — these are internal Siemens ordering keys, not electrical ratings, but they belong on the purchase order for clean reconciliation against the invoice and the nameplate.
