Wybrane problemy zaburzeń w przemiennikowym układzie napędowym

Mainly this article is connected with electromagnetic interferences in a converter drive system. However, it is rising also on issue an influence of correct selection of the motor cables on performance of electric motor drive system with PWM inverter and on durability of the motor winding isolation and durability of its cables themselves. In the article, the author introduced the problems related with the harmful influence of the cables currents and voltages both on insulation of the motor windings and its duration phenomenas. The principal goal of this article is to familiar of the reader with the problems bounded up with exploitation of the electric drive systems from the side of electromagnetic interferences emission, voltage waves reflection and other phenomenas accompanying of conducting of voltages waves with sharp slopes. The author has reviewed of interference phenomenas in the motor supplying systems working with PWM converters with high chopping frequencies and has represented of the conclusions useful for practical goals in electric drive systems exploitation.
