Patent ID: 10050485

Abstract:
A stator includes a core having inwardly extending teeth, an insulator placed on an end surface of the core, coil windings wound the teeth, outgoing lines extending from both ends of the coil windings, and a yarn securing the outgoing lines to the insulator. The insulator has an outer wall surrounding a central axis and erected to upwardly extend from the end surface, a plurality of teeth cover portions radially inwardly extending from the outer wall, a plurality of inner walls erected at an end portions of the teeth cover portions, and at least one projection portion. The coil windings are placed between the outer wall and corresponding inner walls. At least one passage portion is formed in the outer wall to pass the yarn. The projection portion spaces the outgoing lines from the coil windings and secures the outgoing lines, and radially inwardly extends from the outer wall.
