Abstract

PURPOSE: To suppress the displacement and vibration of risers and raise the mechanical strength of the coupled parts of the risers and commutator segments, by providing projections on the commutator segments at both the sides of riser insertion grooves and filling a material between the risers and the projections.
CONSTITUTION: The projections 14 are provided on the commutator segments 2 at both the sides of the riser insertion grooves 13 in parallel therewith. The material such as solder, resin or cement is filled between the resers 1 and the projections 14 to eliminate gaps between them. Thus, the circumferential displacement and vibration of the risers 1 are suppressed and the mechanical strength of the coupled parts of the risers and the commutator segments 2 is raised.
