MOTOR BOBBIN

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.
