Modernizarea sistemului de tracţiune a motorului de curent continuu pentru troleibuzul articulat UMZ-T1

Abstract

The aim of this paper is to present the upgrade of direct current traction on compound trolleys. Firstly, we will present the actual state and a general description of the compound trolleybus and its control system, the classic resistor command system. Secondly the upgrade of the traction system with an electronic module SDMC-103-05 will be presented. The upgrade of the trolleybus, which is already implemented in Chisinau, will be presented in the modified structure and the benefits it provides.
