WIPO Patent Application WO/2019/073921

Kind Code:

A1

Abstract:

A stator comprises an annular back yoke (511), a stator core (510) having a plurality of teeth (512) that protrude radially inward from the back yoke (511) and that are arrayed with gaps opened therebetween in the circumferential direction, and insulators (520, 530) sandwiching the stator core (510) from both sides in the axial direction. Fitting grooves (515) are axially provided on the outer-circumference side of the back yoke (511) so as to circumferentially flank the position of a crimp (513) across a gap, the crimp joining laminated steel panels of the back yoke (511). Projections (524b, 534b) that fit in the fitting grooves (515) of the back yoke (511) are provided on the outer-circumference side of the insulators (520, 530).
