  • Method of making dynamoelectric machines including metal filled glass cloth slot closure wedges
    Patent number: 5214839
    Abstract: A high permeability slot wedge for a dynamoelectric machine with the wedge configured as an elongated bar of uniform cross-sectional configuration formed of a ferromagnetic material having modestly good electrically insulative properties comprising approximately by weight 60% to 80% relatively small ferromagnetic particles such as powdered iron, about 10% reinforcing glass fabric; and 15% to 20% unsaturated thermosetting plastic resin binder such as a polyester resin is disclosed. The ferromagnetic material is homogeneously distributed throughout the thermosetting plastic binder so that the permeability and resistivity of the resulting wedge is substantially uniform throughout.
    Type: Grant
    Filed: September 15, 1992
    Date of Patent: June 1, 1993
    Assignee: General Electric Company
    Inventors: John C. Rieber, Jeffrey S. McCoy
