Abstract

17,380. British Thomson-Houston Co., [General Electric Co.]. Aug. 18. Homopolar machines; collecting-rings.-Each set of collecting-rings D, D', Fig. 1, of a machine is formed out of a single casting cut in such a manner as to form a number of rings d separated by air spaces, the casting being also provided with interior radial webs d' which serve to connect the riogs electrically and mechanically and also act as vanes to force air through the air spaces. Fig. 1 shows a low-voltage homopolar machine in which the currents are induced in the body of the armature A, which is provided with axial and radial air passages a, a'. The brushes E on each set of collecting-rings are connected together by a conductor F, which is led circumferentially around the end of the machine, as shown in Fig. 4, to produce a magneto-motive force tending to neutralize the stray field at the end of the field magnet B. The leads f<1>, f<2>, f<3> to the brushes are distributed, and connexion to the external circuit is made by the lead f near one end of the conductor F.
