STATOR CORE MANUFACTURING METHOD AND STATOR CORE

摘要

In order to prevent unwanted burr formation on an insulating resin that is provided between a stator winding and a main core block body, the present invention provides a stator core manufacturing method for manufacturing a stator core that is constructed by connecting, into a circular shape, multiple core blocks (11), each being constructed by laminating multiple core pieces (20) together in the axial direction, wherein each core block (11) is equipped with a main core block body (12) that has a yoke section (13) and a magnetic pole tooth section (15), and an insulating resin layer (18) that is provided between a stator winding (25) and the main core block body (12) so as to cover a section that includes the surface of the magnetic pole tooth section (15) around which the stator winding (25) is wound. The stator core manufacturing method includes an injection molding step in which the insulating resin layer (18) is integrally formed with the main core block body (12) for each main core block body (12) by means of injection molding.
