0.75 kW / 3.7 Nm envelope at 400 V 3AC
The 1FL2306-1AC11-1MB0 sits in the active SIMOTICS S-1FL2 line as a low-inertia 400 V 3AC servomotor rated 0.75 kW with a nominal speed of 2000 rpm, a stall torque M0 of 3.7 Nm and a continuous Mn of 3.58 Nm — a small but useful margin between stall and continuous that lets short duty-cycle bursts above the rated load clear without tripping the drive. Mechanical fit is the 65 mm shaft-height frame with an AM21-bit angular connector, a keyed shaft to tolerance N, and an IP65 housing with oil seal — meaning the motor is sealed for cabinet-cooling inlet air and factory-floor washdown duty rather than submerged or high-pressure cleaning.
Paired to SINAMICS S200 PN
Siemens lists this 1FL2 variant as matching the SINAMICS S200 drive family, so the AM21-bit single-cable connector feeds both the power stage and the 21-bit absolute encoder back to the drive in one assembly — no separate resolver cable to land at the panel. The integrated holding brake is sized to hold the rotor at standstill after a controlled stop; braking energy is dissipated in the drive, not in the motor, so the holding brake is a position-holding device, not a dynamic stop element on a moving axis.
Build-to-order, group R220 / X0DM
Siemens classifies the motor as product class C — manufactured to order and not returnable for credit — which is standard for configured servomotors and means a confirmed RFQ typically triggers a factory build slot rather than a shelf-pull. Internal classification is Group Code R220, Product Group X0DM, and the lifecycle stage is recorded as current — so the part is on the active price list, not in last-time-buy or phase-out.
Pack-out and cross-border movement
Export control is AL:N / ECCN:N, so the motor ships without a dual-use export licence into most jurisdictions — useful when the same factory build lands an APAC, EU, or North American machine line through parallel channels. Carton dimensions are 392 x 269 x 286 mm for a single-piece pack, and the lot ships as one piece per quantity unit — straightforward for a sea-freight crate or a consolidated air freight slot.
