W pracy przedstawiono zagadnienia pomiaru i filtracji zaburzeń przewodzonych, wprowadzanych do linii zasilających przez silniki prądu stałego o mocy do 1 kW. Analizie poddano wybrane silniki z komutatorami klasycznymi, wzbudzane magnesami trwałymi i elektromagnesami oraz silnik z komutatorem elektronicznym, wzbudzany magnesami trwałymi. Badania wykonano na specjalnie opracowanym laboratoryjnym stanowisku pomiarowym, sterowanym programem stworzonym w środowisku LabVIEW.
Selected problems of measurement and filtration of conducted disturbances in DC low power supply lines are presented in the paper. Disturbances generated by DC low power electric motors (about 1 kW) were measured and analyzed. The exemplary electric motors with classic and electronic commutators were tested. The usefulness of research the conducted disturbances is explained in chapter 1. For the tests a special laboratory stand was worked out (chapter 2). The block diagram of the measuring path and a photo of laboratory stand are shown in Fig. 1. The measurements of conducted emission levels were performed in the frequency range from 150 kHz to 30 MHz. The software was created in LabVIEW environment. Most important results of research are presented in chapter 3. In the Fig. 4 the filter structure for limiting disturbances is shown. Such filter was used in power lines of EUT. Effectiveness of filter operation in tests of electric motors is presented in Fig. 5, 6. The future directions of the work and a main conclusions are pointed out in chapter 4. The influence of exemplary selected line impedance stabilization network (LISN) on the measuring results is also analyzed in the paper. Measurement error of disturbances ?Um is determined (3). The curve of this error is drawn in Fig. 9. - Źródło:
