摘要： A core insulator fit on a stacked core is formed in a single unit which has tooth cover pieces and coil bobbin piece. The tooth cover pieces are formed to extend in the radial direction and be spaced apart equi-angularly for covering one axial side surface of the stacked core. The coil bobbin piece extends from the corresponding tooth cover pieces in the axial direction to cover the inner side surfaces of slots of the stacked core. The top ends of the coil bobbin piece protrude from the other axial side surface of the stacked core, when the core insulator is fit on the stacked core.

摘要： A stator for a motor includes a stator core, an insulator, and coils. The stator core includes an annular portion and teeth, which extend radially from the annular portion. The stator core is divided into core segments in the circumferential direction. Each core segment has an arcuate portion and one of the teeth, which extends from the arcuate portion. The insulator insulates each coil wound around one of the teeth from the stator core. The insulator includes coupling portions at positions corresponding to the circumferential ends of the arcuate portions. Each coupling portion couples the adjacent core segments to be rotatable relative to each other. The insulator facilitates manufacture of the stator.
