Abstract (en)
[origin: US8635760B2] In a method for producing a commutator ring for a commutator of an electric machine, the lamellae of a commutator ring are formed of an electrically conductive, deformable band material, and they have at least one recess running in the longitudinal direction of the band material, before a desired number of the formed lamellae are closed to form the commutator ring. After the closing of the lamellae to form the commutator ring, a reinforcing ring made of an electrically nonconductive, deformation-resistant material is introduced into the recess and is fixed in the recess by plastic deformation of the lamellae of the commutator ring.
