Siemens 1FL2310-2AC01-0HB0 SIMOTICS S-1FL2 3.5kW 2000rpm 16.7Nm Servo Motor

The Siemens SIMOTICS S-1FL2 (1FL2310-2AC01-0HB0) is a 400 V 3AC servo motor rated for 3.5 kW at 2000 rpm, delivering 16.7 Nm rated torque and 11.0 A rated current with a 90 mm shaft height. It carries a 17-bit singleturn absolute encoder, angular connector, plain shaft, and IP65 protection with an oil seal for pairing with a matching SINAMICS S200 drive.

Selection Notes

At 16.7 Nm rated / 55 Nm maximum torque and a 90 mm shaft height, this sits at the high-torque end of the S-1FL2 line, built for loads well beyond what the 40 mm-frame motors handle. Maximum torque runs at roughly 3.3x the rated value, the headroom available for acceleration ramps and short peaks before the drive current limit intervenes. The oil-seal-equipped IP65 rating (versus the non-sealed IP54 variants in the same family) is the detail that matters when the shaft passes through a washdown zone or an oil-lubricated gearbox interface rather than a clean cabinet. The angular connector orientation is worth checking against the installed cable routing before ordering, since it differs from the hybrid straight-connector variants in the line.

Applications

Higher-torque single-axis motion on conveyor drives, indexing tables, and machine tool feed axes where the load exceeds what a compact-frame servo motor can deliver, driven by a matching SINAMICS S200 servo drive.
