ABSTRACT:
A molded commutator is made up of segments arranged in a ring with their brush contact surfaces facing inwardly and forming a cylindrical shape. A matrix of plastic is molded between and around the outside of the segment ring in order to separate the segments electrically and to hold them in the ring configuration. A reinforcing metal casing serves to contain the commutator against breaking up due to centrifugal forces experienced during rotation. An alternate embodiment uses metal bands embedded within the matrix for this purpose.
