Active build for the SINAMICS S200 line
The 1FL2306-1AC11-1SB0 is a SIMOTICS S-1FL2 low-inertia servo motor in the 65 mm shaft-height frame, sized for the SINAMICS S200 drive family and rated at 400 V 3-phase supply with Pn = 0.75 kW at Nn = 2000 rpm and a stall torque M0 = 3.7 Nm against Mn = 3.58 Nm nominal. Siemens lists as current and the product as Active, so the motor is in normal build rather than a last-time-buy window; it is specified to pair one-to-one with the SINAMICS S200 converter in the same drive ecosystem. Built for panel or machine-mount duty rather than washdown, it carries IP65 with an oil seal on the shaft pass-through and ships with the angular connector, a keyed shaft with N tolerance, and an integrated holding brake.
What the headline numbers mean at the shaft
0.75 kW at 2000 rpm defines a continuous operating point; the 3.7 Nm stall against 3.58 Nm nominal tells the integrator the motor is sized close to its thermal ceiling — short overload headroom only, no margin for a punchy cyclic peak duty. An absolute encoder with 21-bit resolution feeds position back to the SINAMICS S200, so cycle-time and synchronization quality are governed by the drive's bus interface rather than the motor itself; the encoder just sets the commutation accuracy at low speeds.
Mechanical fit and panel integration
65 mm shaft height places this in the low-inertia frame range typical for lightweight handling axes, and the keyed shaft with N tolerance mates to standard couplings without a slip-fit rework. The angular connector orientation is fixed at build; route the cable so the connector body clears the housing envelope, and the IP65 oil seal means the shaft side tolerates light cutting-fluid exposure, not full washdown. Holding brake is integrated, which removes the need for an external fail-safe brake on vertical axes but means the brake coil is in the same power feed as the motor — confirm 24 V brake supply and the drive's brake-control output are wired before commissioning.
Compliance and what ships in the box
The motor has been RoHS-compliant since 01-01-18, falls under REACH Article 33 duty-to-inform (Reach Information is published by Siemens), and is not export-controlled — ECCN and AL are both N. Product class is built-to-order with no return-for-credit path, packaging quantity is one piece in a 392 x 269 x 286 mm shipper, and ordering is by the full 1FL2306-1AC11-1SB0 code — that string fully specifies frame, encoder, brake, connector, and seal.
Sourcing posture for the BOM line
Internal classification fields — Group Code R220 and Product Group X0DM — are Siemens-side ordering handles and do not change the BOM line; they only matter when matching a quote back to a Siemens PO reference.
