ELECTRIC MOTOR BOBBIN STRUCTURE AND METHOD FOR MANUFACTURING SAME

摘要

Provided is an electric motor bobbin structure that is capable of efficiently transmitting heat generated from a winding to a stator core and improving heat-transmission performance. This electric motor bobbin structure is provided with: a stator core (32); a bobbin (36) covering the outside of the stator core (32); a winding (33) wound around the outside of the stator core (32) with a bobbin (36) interposed therebetween; and a mold resin (34) for integrally sealing the stator core (32), the bobbin (36), and the winding (33), and having higher heat conductivity than the bobbin (36). The bobbin (36) also has a winding support part (36a) for supporting the winding (33), and a thickness-removing part (36b) formed on the winding support part (36a) and covered by the winding (33). The mold resin (34) is configured to fill at least part of the thickness-removing part (36b), and to contact the stator core (32) and the winding (33).
