0.75 kW SIMOTICS S-1FL2 on a 200 V 3AC bus
The Siemens 1FL2204-2BG11-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family built for the SINAMICS S200 drive platform, rated 0.75 kW from a 200 V 3AC supply with a rated speed of 3000 rpm and matched standstill and nominal torque of 2.4 Nm — so the motor delivers its full continuous torque across the working speed range without a torque-sag region near base speed. It carries a 40 mm shaft height, a hybrid motor connector, an AS-i 21-bit absolute encoder, a keyed shaft with N tolerance, and an integrated holding brake, with IP65 protection that includes the shaft seal — so the same unit fits machine-tool auxiliaries and small handling axes where oil mist and coolant splash reach the motor face.
Encoder, brake, and shaft — motion-loop detail
The AS-i 21-bit absolute encoder gives 2.097 million counts per turn, so position holding and homing run single-turn clean without an external reference — this is the resolution floor that decides whether a machine-tool axis can hold the micron across a holding-brake engagement. The integrated holding brake is the appropriate match for vertical or horizontal axes that need a fail-safe stop with the drive disabled, and the shaft key with N tolerance gives positive torque transmission without a press-fit coupling — verify the driven element's keyway dimension against the cataloged shaft drawing before assembly. IP65 with oil sealing means the body and the cable entry hold up against coolant and lubricant exposure typical of a machining cell, but the rating applies only when the hybrid connector is fully mated and the cable gland is tightened to its specified torque — an unmated or partially seated connector breaks the seal at the cable face, not the housing.
SINAMICS S200 pairing and the 200 V drive bus
This motor is specified as the matching drive for SINAMICS S200, so the cable set, encoder protocol, and brake control are already configured in the S200 firmware — the integrator configures the motor code in the drive and gets the correct torque, current, and thermal model without manual parameter entry. Running from a 200 V 3AC bus puts this motor in the single-phase/three-phase 230 V class typical of light-machine panels in European and Asian tool-room builds, so the upstream transformer sizing and DC-bus capacitance in the S200 line filter are sized for the 0.75 kW continuous load — no special mains impedance is required at this rating.
Compliance, packaging, and order posture
The product class is built-to-order with no reuse or return against credit, the unit quantity is one piece, and packaging is 382.00 x 222.00 x 240.00 mm — so the order is firm at the time of quotation and the carton is sized for a single motor rather than a multi-pack.
