摘要： In a method for manufacturing a motor bobbin around which a coil is wound, an insulating sheet and a core material are disposed within the cavity of an injection mold, and the motor bobbin is formed by the injection mold into which a resin is injected. The motor bobbin consists of the insulating sheet and a resin molded body.

摘要： Provided is a motor bobbin 1 around which a winding wire is wound, said motor bobbin 1 comprising insulating paper and a resin moulded body 4. The insulating paper and the resin moulded body 4 are coupled and fixed together without using an adhesive agent. Surfaces of the insulating paper which are in contact with the resin moulded body 4 are configured using aramid paper comprising an aramid fibrid and aramid short fibres. Resin is melt extruded and thermal-fusion bonded upon the aramid paper comprising the aramid fibrid and the aramid short fibres, and the surfaces configured from the aramid paper are surface treated to obtain the insulating paper. The motor bobbin 1 is obtained by bringing melted portions of the resin moulded body into contact with the top of the aramid paper.

摘要： A motor bobbin having a bobbin body portion around which a coil is to be wound, and flange portions provided integrally to both end portions of the bobbin body portion, the bobbin comprising: a molded resin article formed by using a polymer having amide linkages, and an insulating paper comprising an aramid paper made of an aramid fibrid and an aramid short fiber, wherein a surface of the molded resin article and the aramid paper are directly bonded to each other. The motor bobbin can cope with an increased efficiency and an increased power output of a motor generator or the like.
