Product description
With frame size 100, the Siemens 1FK7100-5AF71-1DH0 is part of the compact SIMOTICS S-1FK7 motor range. The permanent-magnet synchronous motor has eight poles and, at 100 K, a rated speed of 3,000 U/min, rated torque of 12 Nm and rated current of 8 A. At standstill under the same thermal conditions, the values are 18 Nm and 11.2 A. Power at the optimum operating point is 3.8 kW. The mechanical speed limit is 5,000 U/min, while maximum torque is 55 Nm. The IC22DQ encoder records position incrementally at 22 bit, with an internal resolution of 2,048 signal periods per revolution and an 11-bit commutation position. The mechanical configuration comprises a plain shaft, radial runout tolerance N and a permanent-magnet holding brake. Its holding torque is 23 Nm with a DC 24 V ± 10 % supply. The motor is naturally cooled and manufactured in mounting forms IM B5, IM V1 or IM V3. Power and signal connections use rotatable M23 connectors. The degree of protection is IP64. For installation space, the variant-specific dimension drawing specifies a motor length of 235 mm, a flange dimension of 240 × 240 mm and a shaft height of 96 mm. The moment of inertia is 63.9 kgcm², efficiency is 92 %, and net weight is 21.5 kg. The complete article number identifies the encoder, shaft, brake and connector configuration of this motor version.
