STATOR AND MOTOR
First Claim
1. A stator comprising a plurality of stator segments joined together to define a cylindrical shape, each of the plurality of stator segments including:
- a core segment including a core back portion having a cross section in a shape of a circular arc, and a tooth portion arranged to extend from the core back portion in a radial direction of the stator, the core back portion being joined to the core back portions of adjacent ones of the plurality of stator segments;
a coil wound around the tooth portion and including a pair of coil wire terminals;
an insulating layer arranged between the coil and the tooth portion; and
a resin layer arranged to have the entire coil except for the coil wire terminals embedded therein;
whereinthe resin layers of the plurality of stator segments include a supporting structure defined therein to allow a wiring member to be connected with any of the coil wire terminals to be attached to and removed from the stator.

Abstract
A stator is compatible with a variety of wiring configurations and possesses excellent versatility, while also preventing an increase in the size of a busbar unit. The stator includes a plurality of stator segments joined together to assume a cylindrical shape. Each stator segment includes a core segment including a core back portion and a tooth portion; a coil including a pair of coil wire terminals; an insulating layer arranged between the coil and the tooth portion; and a resin layer arranged to have the entire coil except for the coil wire terminals embedded therein. The resin layers of the stator segments include a supporting structure defined therein to allow a wiring member to be connected with any of the coil wire terminals to be attached to and removed from the stator.
