Abstract

The present invention provides an insulator which comprises: an inner guide; an outer guide; and a body connecting the inner guide and the outer guide, and having a coil wound thereon, wherein a rotatable wing is connected to an outer surface of the outer guide.

First claim

The invention claimed is:

1. A motor comprising:
a stator on which a coil is wound;
a rotor disposed inside the stator;
a rotational shaft coupled to the rotor; and
an insulator located between the coil and the stator and including an outer circumferential surface on which the coil is wound,
wherein the insulator includes an inner guide, an outer guide, a body which connects the inner guide and the outer guide and on which the coil is wound, and a wing rotatably connected to an outer surface of the outer guide, and
a plurality of guide grooves for guiding the coil are disposed on the outer surface of the outer guide.

2. The motor of claim 1 , wherein the wing and another wing adjacent to the wing are connected by a connecting part.

3. The motor of claim 2 , wherein the plurality of wings and the connecting part are integrally injection-molded.

4. The motor of claim 3 , wherein a notch is formed in the connecting part.

5. The motor of claim 3 , wherein a height of the connecting part is smaller than that of the wing.

6. The motor of claim 1 , wherein the wing has a height enough to cover the plurality of guide grooves.

7. The motor of claim 1 , wherein a busbar connecting part connected to a busbar may be formed on the wing.

8. The motor of claim 7 , wherein the busbar connecting part includes a groove into which the busbar is inserted.

9. The insulator motor of claim 3 , wherein a busbar connecting part is formed on at least one of the plurality of wings.

10. The motor of claim 9 , wherein, among the plurality of the wings, a thickness of the wing in which the busbar connecting part is formed is greater than that of the wing in which the busbar connecting part is not formed.

11. The motor of claim 1 , wherein the outer guide and another outer guide adjacent to the outer guide are connected by a connecting part.

12. The motor of claim 11 , wherein a notch is formed in the connecting part.
