03GP 6203 DYNAMOELECTRIC MACHINES INCLUDING METAL FILLED GLASS CLOTH SLOT CLOSURE WEDGES, AND METHODS OF MAKING THE SAME ABSTRACT OF THE DISCLOSURE 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.
