  • Publication number: 20210184528
    Abstract: In an armature, a plurality of segment conductors, which are joined to each other at a joint portion, are disposed in parallel in the radial direction. An insulating portion is provided on a conductor surface of one segment conductor at a position in the center axis direction corresponding to an adjacent joint portion of a different segment conductor that is adjacent to the one segment conductor in the radial direction. The insulating portion has a second insulation resistance which is higher than a first insulation resistance of an insulating coating of the different segment conductor.
