Tests of the electromagnetic compatibility of selected elements of industrial automation

The practical part presented in the work was devoted to the study of electromagnetic compatibility of two systems being elements of industrial automation. The first of these systems was built from SEW-Eurodrive components: frequency inverter and electric motor. Research was carried out twice using laboratory stands with two types of clamps: CDN (Charge Device Model) clamps and EM (Electromagnetic Model). The second system was the capacitive sensor. In this case, the tests took place only on the EM clamping bench. Thanks to this, during the tests, it was possible to check the function of the capacitive sensor when the direction of the generated interference was consistent or opposite to the direction of the sent object detection signal by the sensor. In both cases it was possible to determine the frequency values at which the sensor was malfunctioning. By performing further tests, the distance at which the sensor did not interrupt work was determined and compared with the manufacturer's data.
