摘要:
A coil of a dynamoelectric machine is constituted by forming a conductor (22) that is the coiled aggregate of flat strands (21) under Rebel dislocation, by winding layers of a mica tape (71), consisting of mica paper (5) and reinforced glass cloth (6), around the outer periphery of the conductor (22), and by impregnating the wound layers of the mica tape (71) with a resin and curing it. An inorganic powder (14) is carried by the reinforced glass cloth (6) of the mica tape (71) with an adhesive (13) which contains a size insoluble to the impregnating resin as an essential component.
摘要:
A coil for an electric rotating machine is configured with a conductor (22) which is formed by bundling a plurality of square strands (21) and stacking the square strands like a coil with Roebel transposition, mica tape (71) which is wound a plurality of layers around an outer surface of the conductor (22) and made up of mica paper (5) and glass cloth backing (6), and an insulation wall (8) formed by impregnating and curing resin between wound layers of the mica tape (71). Inorganic particles (14) are supported with the glass cloth backing (6) on the mica tape (71) using an adhesive (13) containing glue insoluble in the impregnated resin as an indispensable component.
