Siemens 1FL6044-1AF61-2AA1 SIMOTICS S-1FL6 400V 0.75kW 3000rpm Servo Motor

The Siemens 1FL6044-1AF61-2AA1 is a SIMOTICS S-1FL6 servo motor rated 0.75 kW at 3000 rpm with a 3AC 400 V supply, delivering 2.39 Nm rated torque and 7.20 Nm maximum torque. It has a 45 mm shaft height, IP65 protection, and a 2500-pulse incremental encoder, compatible with SINAMICS V70 and V90 drives.

Technical Specifications

Selection Notes

The 400 V 3AC winding on this SH45-frame motor connects directly to SINAMICS V70/V90 drives at line voltage without a step-down transformer, unlike lower-voltage windings in the same shaft-height class. Rated torque of 2.39 Nm against a 7.20 Nm maximum gives roughly 3x overload margin for acceleration and short-duration disturbances typical of pick-and-place or indexing axes. IP65 sealing with the supplied sealing ring suits washdown-adjacent or dusty machine environments without an added enclosure; this variant ships without a holding brake, so the axis will not hold position on power loss.

Applications

Servo axis drive for packaging, pick-and-place, and general motion-control machines using SINAMICS V70 or V90.
