Technical devices that use electric machines with brush sliding contact stillrepresent a large part of utilized drives. In wide variety of applications for carbon brushes such as mining, vehicles with battery drive, aerospace, cosmonautics,power engineering, traction, industry, and many other areas, proper selection of the sliding contact elements, mainly carbon electric brushes, is a prerequisite for failsafe work, to obtain the Best performance and lowest operating costs. In recent years, due to the generational exchange of technical personnel in industry, more and more often one does not see the importance of maintaining a professional approach to the technical efficiency of electrical machines with sliding contacts. In this study we present few selected fromrecent years, typical operational problems,identified by the company's specialists from Elektrocarbon in Tarnowskie Gory. Often, problems arose from failure tothe technical rules of proper selection of replacement part to sliding contact: brush holder or brush. In this study have been discussed following examples of failure and disruption of machines that have occurred in: asynchronous slip-ring motors used in conveyor belt drives in coal open-pit mines, the comutatorgenerator supplying winder in a coal mine, the railway engine of modernized electric locomotives. In each of these cases method of how problems were successfully solved was presented.
