It draws its catalog identity from the Siemens 1FK7 high-dynamic family, so nameplate, encoder variants, and shaft options stay with the SIMOTICS S naming on the type plate — a useful cross-check when a replacement motor arrives without its full box. Panel-side, a 0.82 kW / 3 Nm motor of this class mounts through a flange or face-mount foot pattern and lands on a SINAMICS drive over the DRIVE-CLiQ or conventional resolver/encoder path typical of the 1FK7 generation. PN=0.82 kW at NN=3000 rpm sets the continuous operating point — with M0=3 Nm held as the stall torque at the 100 K winding class, the motor has the torque headroom to absorb short peak loads above continuous rating before the drive's thermal model flags derating. UDC=600 V names the permitted DC-link ceiling on the converter bus, so the matching SINAMICS drive must sit at a DC-link voltage below that figure; this is the number that drives drive selection, not a standalone mains rating. Naturally cooled implies no integrated fan — sizing should budget the motor's own thermal rise into the enclosure's ambient rather than assume forced ventilation, which becomes a limiting factor when retrofitting into a sealed cabinet. ## Lifecycle posture and documentation Compliance documentation expectations for a SIMOTICS S-1FK7 motor of this frame typically follow the standard Siemens CE, UKCA, and UL-relevant declarations under the SIMOTICS family; specific certificates are not carried in this evidence and should be requested against the unit's serial number rather than the order code alone.","metaTitle":"1FK7042-2AF7.-....
