Problemy pracy silników elektrycznych zasilanych z układów przemiennikowych

In the present time, in industry, one is using a lot of power converters systems for the work with AC electric motor drives. They have various applications: pumps, compressors, fans, grinding machine drives, and so on. Also in this time much of them are in household and industrial HVACs. Depending on application, one make those drives various requirements: high level of efficiency, noiseless work, wide range of motor speed, e.t.c.. In these systems however, important also remains phenomenon of influence of the inverters output on theirs motors work. This paper is connected with the subject. Author of the article has presented the problems making classifications of these phonemes and he done their analysis in further part of this work. This paper is completed by the conclusions after analysis of above discussed phonemes.
