Abstrakt v dalším jazyce:	The most common cause of mechanical failure of brushed electric motors is the damage to the commutator and brushes but in harsh environments also mechanical damage to the bearings occurs. One of the main grounds of bearing damage is an unsuitable lubricant, various microparticles entering the lubricant on grinding poor quality bearing parts or inclusions related to the mechanical wear of the commutator. We examined the foreign substances or particles in the grease (petroleum jelly) of the bearing by Energy Dispersive X-ray Spectroscopy (EDS) of the components of a used commutator and of a new one. After disassembling the bearing, we analysed the cage, balls, grease and inner ring of the bearing. The obtained results indicate that the undesirable properties of the studied bearing are related to defects in the metallic components of the bearing and to the content of impurities in the lubricant.
