Abstract

116,226. Marks, E. C. R., (Akt.-Ges. Brown, Boveri, et Cie). Dec. 17, 1917. Commutators which are fixed by means of shrunk rings s and wherein the brushes rub on the cylindrical periphery of the commutator are provided with an increased heatradiating surface comprising annular bosses a formed on the bars l and adapted to receive the rings s, the diameter of the bosses being considerably greater than that of the rubbing surfaces for the brushes. Vanes w may be formed on the rings or on the bosses a. Air-conducting passages, such as k, are described, traversing the rings s and the bosses a in various ways.
