What it is and which drive it pairs with
The 1FL2104-4BF11-1SC0 is a Siemens SIMOTICS S-1FL2 low-inertia servo motor in the 1FL2 family sized specifically for the SINAMICS S200 drive platform, which means cabling, encoder protocol, and electronic nameplate are set up for that pairing rather than for a generic S210 or S120 retrofit. Rated 400 V 3AC supply with 1 kW rated power (Pn), 3000 rpm rated speed (Nn), and both stall torque M0 and rated torque Mn at 3.2 Nm — the equal M0/Mn figure flags a low-inertia rotor profile, which suits point-to-point positioning and fast acceleration/deceleration duty more than constant-torque conveyor service.
Mechanical and feedback build
Shaft height 40 mm with a keyed shaft (tolerance N) and a factory-fitted holding brake — the brake is specified in the order code so the brake variant, voltage, and backlash class are fixed at build time, and any field retrofit would require a factory-returned exchange rather than a separate brake kit. Feedback is an absolute encoder, 21-bit single-turn (AS21 bit) brought out on a hybrid connector — the hybrid connector carries power and signal in one shell, so the cabinet-side mating connector and the cable stock must be the matching Siemens hybrid type, not a plain M23 power plus separate signal pair. Protection class IP65 with oil seal on the shaft, which makes the motor suitable for machine tools and gearboxes where cutting oil or lubricant splash reaches the shaft seal; IP65 is not full washdown, so for food-and-beverage or outdoor mounting a higher-rated housing or a protective shroud is still needed.
Lifecycle and compliance status
Compliance paperwork available on the manufacturer's record: RoHS conformity since 01-01-18 and REACH Article 33 duty-to-inform per the current SVHC candidate list; export-control classification shows AL:N / ECCN:N, which means no special export licence is required for routine cross-border shipments of this motor. Product class is C — built to order, not a stocked catalogue item that can be returned for credit — so the order code (shaft, brake, encoder, connector, seal) is final once the production order is released.
Order-code identifiers for tender and MRO paperwork
Supplied as one piece per package, with shipping/handling carton dimensions 382.00 x 222.00 x 240.00 mm — sized for a single-motor pack rather than a multi-pack, which is the standard configuration for a built-to-order servo motor.
