PURPOSE:To improve the sliding characteristic of a commutator and to prevent the life of a motor from shortening by providing atmosphere of one or more of specific medicines having no benzene ring in a case of a motor having a brush and the commutator. CONSTITUTION:In a motor in which a commutator slide 3 is slid with commutator segments 4, atmosphere is formed by impregnating a felt 16 with one or more of paraffins, monoalcohols, polyvalency alcohols, ethers, cyclic ethers, ketons, ether alcohols, ester alcohols, esters, aminoalcohols, fatty acids, alkylamides, first class amines, second class amines, third class amines, and singlecyclic oxyterpenes having no benzene ring in a motor case. |
