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.","metaTitle":"Siemens 1FL2104-4BF11-1SC0 SIMOTICS 1FL2 servo, 1 kW, IP65","metaDescription":"Siemens 1FL2104-4BF11-1SC0 SIMOTICS S-1FL2 servo, 400 V 3AC, 1 kW, 3000 rpm, 3.2 Nm, IP65 with holding brake; paired with SINAMICS S200.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Servo Motors"],"specifications":{"title":"1FL2104-4BF11-1SC0","Group Code":"R220","description":"SIMOTICS S-1FL2 Supply voltage 400V 3AC Pn=1kW;Nn=3000rpm M0=3.2Nm;Mn=3.2Nm Shaft height 40mm With hybrid connector AS21bit With shaft key, Tolerance N With holding brake Protection class IP65 with oil Matching drive SINAMICS S200","Product Group":"X0DK","Product class":"C: products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit.","Quantity Unit":"1 Piece","Product Family":"1FL2 servomotors for SINAMICS S200","lifecycle_stage":"current","Packaging Quantity":"1","Export Control Regulations":"AL : N / ECCN : N","Packaging dimensions (L x W x H)":"382.00 x 222.00 x 240.00 mm","Compliance with the substance restrictions according to RoHS directive":"Since: 01-01-18","REACH Art. 33 Duty to inform according to the current list of candidates":"Reach Information"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c9675f62fac779dc502d61882ef50e43.pdf","sourceUrl":"https://sieportal.siemens.com/en-ae/products-services/detail/1FL2104-4BF11-1SC0?tree=CatalogTree"},"ai":{"faq":[{"question":"What ratings and mechanical build define 1FL2104-4BF11-1SC0?","answer":"It is a SIMOTICS S-1FL2 servo, 400 V 3AC supply, 1 kW rated power (Pn), 3000 rpm rated speed (Nn), 3.2 Nm stall and rated torque (M0 = Mn), shaft height 40 mm, keyed shaft with tolerance N, integrated holding brake, absolute encoder 21-bit single-turn (AS21 bit) on a hybrid connector, and IP65 protection with oil seal.
