Product description
Rated torque of 15.5 Nm at 3,000 min⁻¹ defines the Siemens 1FK6101-8AF71-1EB0 within the 1FK6 series. This permanent-magnet AC servomotor has an 8-pole design and reaches a standstill torque of 27.0 Nm at 100 K; the specified value at 60 K is 22.4 Nm. Its corresponding rated current is 10.8 A. Mechanically, this version is equipped with a keyed shaft, runout tolerance N and an integrated holding brake. The letter E in the complete order number identifies the EnDat absolute encoder A-2048. It records 2.048 periods per revolution and 4.096 coded revolutions through a serial EnDat interface. The motor follows mounting arrangement IM B5 and can also be installed in positions IM V1 and IM V3. Its housing is self-cooled and this configuration does not include a separately driven fan. The final character of the order number identifies protection class IP64. For mechanical planning, the Siemens dimensional drawing specifies a shaft height of 100 mm, a square flange outline of 240 × 240 mm and a housing length of 291 mm to the flange face with an optical encoder. Shaft extension is 80 mm. The version with holding brake weighs 28 kg. Documented mechanical limits are 4,300 min⁻¹ and 80 Nm. Separate power and encoder connections use rotatable plugs. A KTY84 temperature sensor in the stator winding monitors motor temperature. Flange and shaft tolerances follow DIN 42955 and DIN 6885.
