Product description
The Siemens 1FT6044-1AF71-3EG1 is a permanent-magnet synchronous servo motor from the SIMOTICS S 1FT6 series. The Siemens Mall data record assigns the complete order number to motor type 1FT6044 with 5.0 Nm stall torque at a winding overtemperature of 100 K and 3000 min⁻¹ rated speed. Natural cooling works without a separate fan assembly. IP65 protection is documented for the housing; the mechanical construction corresponds to IM B5 and can be arranged in mounting positions IM V1 and IM V3. Variant 3EG1 has an EnDat absolute encoder with 2048 signal periods per revolution. Power and signal connections use plug connectors and point axially toward the non-drive end. This order number does not include a holding brake. The Siemens configuration manual specifies four poles, 4.3 Nm rated torque and 2.9 A rated current for the 1FT6044-1AF71 version. Stall torque at 100 K is 5.0 Nm, with 3.0 A stall current. The stated mechanical limit speed is 7700 min⁻¹, maximum torque is 18 Nm and maximum current is 11 A. Without a brake, motor inertia is 5.1 × 10⁻⁴ kgm². The documented torque constant is 1.68 Nm/A. The exact variant-bound dimensional record specifies 320 mm length, 120 mm width and 130 mm height. Siemens states a net weight of 8.3 kg. Natural cooling, IP65 and the absolute encoder describe the factory-coded version rather than a subsequently derived option. The complete order number, encoder version, connector orientation and absence of a holding brake together distinguish this motor variant technically.
