Siemens 1FL2203-4AG00-0HC0 SIMOTICS S-1FL2 Servomotor 400W 3000rpm 200V Servo Motor

The Siemens 1FL2203-4AG00-0HC0 is a SIMOTICS S-1FL2 servo motor rated 400 W at 3,000 rpm, delivering 1.27 Nm rated torque from a 200 V 3AC supply. It pairs with the SINAMICS S200 drive and carries a 17-bit absolute singleturn encoder on a hybrid connector. The plain shaft ships without a holding brake, in IP54 protection without an oil seal.

Selection Notes

This variant shares the 60.2 mm flange and 30 mm shaft height of the 200 W motor in the same series but stretches overall length to 91.5 mm to fit a longer stack, taking rated torque to 1.27 Nm at the same 3,000 rpm rated speed. Static and rated torque are equal, so holding load matches running load, with a 4.45 Nm peak available for acceleration. Rated current of 2.40 A against an 8.70 A peak gives roughly 3.6x current headroom on the SINAMICS S200 loop. Within the 30 mm shaft-height family, this is the higher-torque option; pick the shorter-stack sibling when axial space is tighter and 0.64 Nm is enough.

Applications

Natural cooling and IP54 protection without an oil seal fit panel-mounted or lightly enclosed installations rather than washdown areas. The 1.27 Nm rated torque suits conveyor drives, rotary tables, and feed axes that need more continuous torque than the smaller 1FL2 frames without moving to a larger shaft height.
