Product description

Siemens 1FT5074-1AC71-1AB0 is a permanent-magnet AC servo motor from the 1FT5 series. The AC71 winding is documented with a rated speed of 2,000 min⁻¹. Rated torque at 100 K is 14 Nm and rated current is 9.3 A. Standstill torque is specified as 14 Nm at 60 K and 18 Nm at 100 K. Maximum values are 3,200 min⁻¹, 56 Nm and 45 A. Torque constant is 1.64 Nm/A and voltage constant is 186 V per 1,000 min⁻¹. Winding resistance is 1.2 Ω and winding inductance is 13.2 mH. Core-type code 1AB0 denotes the transverse-right connector direction, integrated tachogenerator and rotor-position encoder system, keyed shaft and integrated holding brake. Size 1 connector is assigned to this motor size. Axial overall length including the shaft is 308 mm. The square flange and maximum transverse dimension each measure 142 mm. Complete outside dimensions are therefore 308 × 142 × 142 mm. Documented weight of the version with holding brake is 19.5 kg. The complete designation 1FT5074-1AC71-1AB0 binds winding, connector direction, encoder, shaft and brake version to this exact variant. Shaft diameter is 24 mm and the shaft projects 50 mm beyond the mounting face. Flange centering diameter is 130 mm.
