Siemens 1FL6094-1AC61-2AA1 SIMOTICS S-1FL6 5kW 2000rpm 400V IP65 Servo Motor

The Siemens 1FL6094-1AC61-2AA1 is a SIMOTICS S-1FL6 servo motor rated 5 kW at 2000 rpm with 30 Nm static torque, built for 3AC 400 V operation and paired with SINAMICS V70 or V90 converters. It carries an IP65 rating with a 2500 increment/rev incremental encoder and a 90 mm shaft height.

Selection Notes

At 30 Nm static torque and 5 kW rated power, this is the higher-torque member of the 1FL6 90 mm shaft-height family - pick it over a lower-power sibling when the load needs more continuous torque at the same 2000 rpm rated speed. Max current of 36.9 A against a 12.6 A rated current gives roughly 3x overload headroom for acceleration. Natural, non-forced cooling keeps wiring simpler than a fan-cooled frame but caps continuous output at the rated 5 kW and 40 degree C ambient. Because the encoder is incremental TTL rather than absolute, the application needs a homing routine on power-up.

Applications

Servo axis drive for machine tools, packaging equipment, and material-handling systems running on SINAMICS V70 or V90 drives, where the compact 90 mm frame at 5 kW / 2000 rpm and IP65 sealing suit washdown-adjacent or dusty panel environments.
