Analysis of the possibility of using LC passive filtration methods in reducing the radiated emission of brushed universal motors

The influence of electromagnetic fields on human organisms is currently a popular direction of research in numerous research centers around the world. The article deals with the measurement of the radiated component of the electromagnetic field, which accompanies the operation of the still popular universal commutator motors and the passive method of its reduction. The research on the radiated component of the electromagnetic field was carried out with the aim of exposing users of home appliances and power tools, especially those located in the immediate vicinity. The measurements were carried out in two stages. Initially, emission parameters were acquired without LC elements, limiting the radiated components of the electromagnetic field. Then, these elements were introduced and the effectiveness of emission reduction was analysed. The results were briefly analyzed and referred to the currently applicable legal acts.
