Abstract

A stator which may enhance processability and manufacturing efficiency and a motor using the same are provided according to an embodiment of the present invention. Particularly, a stator which includes a plurality of unit stator cores which are provided with a tooth protruding from a head portion, an insulator coupled to the unit stator core, and a guide portion having a terminal mounting groove provided at an upper end of the insulator, is provided.

First claim

What is claimed is:

1 . A stator comprising:
a plurality of unit stator cores of which are provided with a tooth protruding from a head portion; an insulator coupled to the unit stator core; and a guide portion having a terminal mounting groove provided at an upper end of the insulator.

2 . The stator of claim 1 , further comprising a neutral point terminal member mounted on the terminal mounting groove and contact-coupled with an end portion of a coil wound around the unit stator core.

3 . The stator of claim 2 , wherein the neutral point terminal member includes a body portion fitted in and coupled to the terminal mounting groove, and a plurality of binding portions provided at the body portion and coupled with the end portion of the coil wound around the unit stator coil.

4 . The stator of claim 3 , wherein the neutral point terminal member are bent to form the binding portions as a structure which surrounds the end portion of the coil.

5 . The stator of claim 4 , wherein the body portion and the binding portions are provided as an integrated structure.

6 . The stator of claim 3 , wherein the neutral point terminal member further includes an anti-rotation protruding pattern coupled to an inner surface of the guide portion at a portion of the body portion.

7 . A motor comprising:
a motor housing; and a stator and a rotor installed in the motor housing, wherein the stator includes: a plurality of unit stator cores which are provided with a tooth protruding from a head portion; an insulator coupled to the unit stator core; a guide portion having a terminal mounting groove provided at an upper end of the insulator; and a neutral point terminal member mounted on the terminal mounting groove and contact-coupled with an end portion of a coil wound around the unit stator core, wherein the neutral point terminal member includes: a body portion fitted in and coupled to the terminal mounting groove; and a plurality of binding portions provided at the body portion and coupled with the end portion of the coil wound around the unit stator core.

8 . The motor of claim 7 , wherein the neutral point terminal member further includes an anti-rotation protruding pattern coupled to an inner surface of the guide portion at a portion of the body portion.
