A structure for bleeding off static electric charges includes a pyrolyzed glass fiber layer having resistivity in the range of 200 to 10,000 ohms per square.

Electric charge bleed-off structure using pyrolyzed glass fiber

A semi-conducting pyrolyzed glass fiber layer equalizes the electrical potential on the exterior surface of an insulated conductor when the layer covers the surface. The layer prohibits the development of a corona discharge and bleeds off any electrical charge developed thereon when the layer is electrically coupled to a body having a known potential. The insulated conductor may be windings in a dynamoelectric machine.

A process for electrodepositing mica and a water soluble anionic resin binder, such as a modified polyester resin, is disclosed as a means for applying a heavy coating of a high-voltage, mica-bearing electrical insulation onto uninsulated and porous mica tape-insulated portions of electrical connections in dynamoelectric machines. The electrodeposited mica coating is subsequently impregnated with a suitable resin, such as an epoxy or polyester resin, concurrently with the impregnation of other conventional insulations in the machine. Alternatively, deposition and impregnation of the connection insulation can be performed prior to installing the connection into the machine.

A stator core for a dynamoelectric machine includes two pairs of dovetail slots disposed at respective predetermined radial positions in each armature slot. All stator slots contain armature bars. A few equally spaced stator slots also contain 'P' bars atop or radially inward from armature bars. Wedges are installed in the radially outer dovetail slots of stator slots containing only armature bars. Wedges are installed in radially inner dovetail slots in stator slots containing both armature bars and 'P' bars.

A composition for electrodeposition of an insulating mica coating onto a conducting substrate is disclosed. The composition consists essentially of mica, a water soluble anionic resin binder, an electrolyte and a polar solvent.
