Rezumat: In aceasta lucrare se analizeaza perturbatiile produse de micromotoarele universale utilizate in constructia echipamentelor electrocasnice. In acest scop se prezinta particularitatile de functionare ale acestora in curent alternativ, cu accent pe fenomenul de comutatie si masurile de imbunatatire a acesteia. Lucrarea prezinta o serie de incercari experimentale efectuate cu un motor universal pentru o rasnita de cafea, alimentat direct de la retea sau prin intermediul unor filtre special proiectate pentru imbunatatire compatibilitatii electromagnetice.

Cuvinte cheie: perturbatii, micromotoare universale, filtre, masurarea curentului

Abstract: This paper analyzes the disturbances caused by universal fractional horsepower motors used in electrical domestic equipments construction. In this purpose there are presented their features for alternating current operation; the accent is laid on the commutation phenomenon and on the methods necessary for improving it. The paper presents many experimental tests performed with a universal fractional- horsepower motor for a coffee mill; the motor is directly supplied or by means of some filters especially designed for improving the electromagnetic compatibility.

Keywords: disturbances, universal fractional-horsepower motors, filters, current measuring
