Case 2596 IMPROVED COMMUTATOR CONSTRUCTION ABSTRACT OF THE DISCLOSURE An improved commutator construction for a commutator having copper commutator segments spaced around the periphery of a commutator support cylinder with an insulating layer between the cylinder and the segments, uses bands of glass fiber in epoxy resin to hold the commutator segments to the support cylinder. A spring segment under compression is used between adjacent commutator segments to provide a force in the peripheral direction to permit expansion and contraction while maintaining the concentricity of the commutator. Mica strips insulate the spring segment from adjacent commutator segments.
