Abstract
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.
