Siemens 1FL2310-4AC01-0HB0 SIMOTICS S-1FL2 Servomotor 5kW 2000rpm 400V Servo Motor

The Siemens 1FL2310-4AC01-0HB0 is a SIMOTICS S-1FL2 servo motor rated 5 kW at 2,000 rpm, delivering 23.9 Nm rated torque from a 400 V 3AC supply. It pairs with the SINAMICS S200 drive and carries a 17-bit absolute singleturn encoder on an angular connector. The plain shaft runs without a holding brake, in IP65 protection with an oil seal.

Selection Notes

Unlike the smaller shaft-height frames in this series where static and rated torque are numerically equal, this 90 mm frame shows 25.2 Nm static torque against 23.9 Nm rated torque, so the thermal continuous rating sits slightly below the zero-speed holding torque at this power class. Static current of 12.60 A equals rated current, while the 36.90 A maximum current gives roughly 3x headroom to the 70.0 Nm peak torque for high-inertia starts. IP65 with an oil seal and an angular connector, in place of the hybrid connector and IP54 rating on the smaller frames, mark this as the variant built for higher-ingress environments and a lower rated speed of 2,000 rpm. Choosing this frame over the lighter shaft-height variants in the series comes down to needing continuous torque above roughly 8 Nm.

Applications

IP65 sealing with an oil seal supports installations with dust or occasional liquid exposure that the IP54 frames in this series are not rated for. The 23.9 Nm continuous torque and 70 Nm peak fit heavier feed axes, large rotary tables, and winder or extruder drives on a SINAMICS S200 system.
