Abstract

21,936. Midgley, A. H., and Vandervell, C. A. Oct. 16. Armatures; field magnets.-The shaft a of a direct - current machine carries a drum armature b, and a frame c which supports a concentric ring-shaped armature d. The annular space between the armatures contains the field magnets e, which are carried by a frame f, forming part of one of the bearings g. Each armature thus forms the yoke of the other. Separate commutators h may be used, or one only may be arranged on the left-hand side and connected to both armatures.
