Реферат: 185,731. Suczek, R., and Sousedik, J. Aug. 30, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Brush-holders; commutators; exciting.-Commutators are insulated by air spaces extending throughout the full cross section of the segments. Figs. 1 and 3 show the invention applied to a selfexciting three-phase synchronous generator, the commutator of which consists of segments a held in position by flanges b, c secured to the stator cover by a split ring d. An extra armature winding on the stator is connected to the commutator and serves to excite the machine. The commutator is preferably constructed by slotting a ring having the cross-section shown in Fig. 5 to form the segments, a solid portion f being retained until the segments are clamped between the flanges b, c. The brushes g are pressed against the commutator by centrifugal force.
