Abstract

Provided is a rotor including a rotor core, a plurality of teeth disposed at an outer side of the rotor core, and an insulator configured to surround the teeth wherein the teeth are detachably coupled to the rotor core, the insulator includes a body configured to surround the teeth, and a blade configured to protrude from at least one of an upper surface and a lower surface of the body, and thereby the number of manufacturing components is reduced and manufacturing costs and the number of manufacturing processes are reduced.

Claims

1. A rotor comprising:

a rotor core;

a plurality of teeth disposed at an outer side of the rotor core; and

an insulator configured to surround the teeth,

wherein the teeth are detachably coupled to the rotor core, and the insulator includes a body configured to surround the teeth and a blade configured to protrude from at least one of an upper surface and a lower surface of the body.

2. The rotor of claim 1, wherein the insulator includes a coupling slot concavely formed on a first side surface thereof and a coupling protrusion convexly formed on a second side surface thereof.

3. The rotor of claim 1, wherein the insulator includes a first coupling slot concavely formed at an upper portion of a first side surface and a first coupling protrusion convexly formed at a lower portion of the first side surface.

4. The rotor of claim 3, wherein the insulator includes a second coupling protrusion convexly formed at an upper portion of a second side surface and a second coupling slot concavely formed at a lower portion of the second side surface.

5. The rotor of claim 1, wherein the blade is obliquely formed to form a receiving angle with respect to a reference line formed in a radial direction from a rotational center of the rotor.

6. The rotor of claim 1, wherein the rotor core includes an assembling slot concavely formed on an outer circumferential surface thereof in an axial direction of the rotor and an assembling protrusion formed at an inner end part of the teeth to be inserted into the assembling slot.

7. A motor comprising:

a rotating shaft;

a rotor through which the rotating shaft passes; and

a stator disposed at an outer side of the rotor,

wherein the rotor includes;

a rotor core;

a plurality of teeth disposed at an outer side of the rotor core; and

an insulator configured to surround the teeth,

wherein the teeth are detachably coupled to the rotor core, and

wherein the insulator includes a body configured to surround the teeth, and a blade configured to protrude from at least one of an upper surface and a lower surface of the body.

8. The motor of claim 7, wherein the insulator includes a coupling slot concavely formed on a first side surface thereof and a coupling protrusion convexly formed on a second side surface thereof.

9. The motor of claim 7, wherein the insulator includes a first coupling slot concavely formed at an upper portion of a first side surface and a first coupling protrusion convexly formed at a lower portion of the first side surface.

10. The motor of claim 9, wherein the insulator includes a second coupling protrusion convexly formed at an upper portion of a second side surface and a second coupling slot concavely formed at a lower portion of the second side surface.

11. The motor of claim 7, wherein the blade is obliquely formed to form a receiving angle with respect to a reference line formed in a radial direction from a rotational center of the rotor.
