Servomotor identity and headline ratings
The Siemens 1FL2310-0AC11-0MB0 is a SIMOTICS S-1FL2 servomotor in the 1FL2 family built for pairing with the SINAMICS S200 drive, with a 400 V 3AC supply, rated power Pn of 2.5 kW, rated speed Nn of 2000 rpm, standstill torque M0 of 12.6 Nm, and continuous torque Mn of 11.9 Nm at shaft height 90 mm. A 2.5 kW continuous rating with 12.6 Nm of standstill torque places this motor squarely in the mid-range dynamic axis class — sized for machine-tool feed axes, packaging index tables, and small-format converting or printing webs where the load inertia is modest but the cycle rate demands the SINAMICS S200 dynamic response envelope. Shaft execution is plain with tolerance N, the encoder is the 21-bit AM21 absolute multiturn read via angular connector, and the housing carries a holding brake for vertical-axis or gravity-loaded hold requirements.
Mechanical and environmental envelope
Protection class is IP65 with oil seal — the seal and shaft seal together let the motor sit adjacent to a gearbox or ball-screw where oil mist and coolant splash are expected, but the rating is not for direct washdown or submerged duty.
Lifecycle status and procurement posture
Lifecycle stage is recorded as current and the product is listed as Active, so the order code remains a live BOM position rather than a last-time-buy.
