Abstract:
A non-micaceous commutator cone for insulating commutator bars from retaining rings of a commutator assembly in a dynamoelectric machine, comprising an annular laminated member including at least one layer of non-conductive, resin-impregnated fibrous elements sandwiched between outer layers of thin, seamless, impervious, non-thermoplastic polymeric films. The wall of this laminate has the dielectric strength, the uniform thickness, the stability, and the resiliency that are required for a commutator cone in a relatively large, high temperature machine.
