SIMOTICS S-1FL2 in the 100 W slot of the SINAMICS S200 kit
The Siemens 1FL2102-4AG11-0SC0 is a member of the SIMOTICS S-1FL2 low-inertia servo family, sized as a 200 V 3AC, 100 W motor with a rated speed of 3000 rpm and a continuous torque of 0.32 Nm at standstill (M0 = 0.32 Nm, Mn = 0.32 Nm). It ships with a hybrid connector, an integrated holding brake, plain shaft with tolerance N, IP65 sealing with oil seal, and a 21-bit feedback — all on a 20 mm shaft-height frame. It is matched specifically to the SINAMICS S200 drive line, so it is not a stand-alone motor — the drive side has to be the corresponding S200 unit for the resolver/encoder protocol and the 200 V 3AC bus to line up cleanly.
What the ratings mean when sizing this motor into a small-format axis
At 100 W and 0.32 Nm continuous (equal standstill and rated torque per the description block), this is the entry-level torque package in the S-1FL2 range — suited to small-format positioning axes such as indexing tables, light feeders, label and dispensing heads, or end-effectors where inertia and torque, not speed, drive the dimensioning. The 3000 rpm rated speed combined with the 200 V 3AC supply tells you the drive commissioning window is the low-voltage, low-power S200 tier; derating curves above the rated point are the standard S-1FL2 family curves, not a per-motor exception. The IP65 + oil-seal combination means the motor body tolerates plant-side splash and coolant mist typical of small machine-tool and packaging environments — but it is not a sealed washdown motor, so cable entries and the connector gland must be respected on the install.
Compliance and documentation pack a validation engineer will want on file
There is no UL or IEC certification line carried in the spec block — those approvals, if required for the end equipment, sit on the drive or the machine assembly, not on this motor entry alone. The product is classed as made-to-order (class C: produced to order, not reusable or returnable against credit) and ships one piece per package in a 315 × 182 × 172 mm carton — relevant when reconciling incoming inspection against the purchase order, because surplus/return credit is not the channel this part runs on.
