## Abstract

Provided is a motor which includes a housing and a stator disposed in the housing and a rotor disposed in the stator and a busbar disposed on one side of the stator, wherein the stator includes a stator core and a coil wound around the stator core and an insulator disposed between the stator core and the coil, the insulator includes a first insulator and a second insulator wherein the busbar includes a guide, wherein the guide is disposed between a first insulator and a second insulator.

## Claims

### Claim 1

A motor comprising:
a housing;
a stator disposed in the housing;
a rotor disposed in the stator; and
a busbar disposed on one side of the stator,
wherein the stator includes:
a stator core;
a coil wound around the stator core; and
an insulator disposed between the stator core and the coil,
wherein the insulator includes:
a first insulator; and
a second insulator; and
wherein the busbar includes a guide,
wherein the guide is disposed between a first insulator and a second insulator.

### Claim 2 (depends on 1)

The motor of claim 1, wherein the guide is provided as a plurality of guides, and each guide of the plurality of guides is disposed between a first insulator and a second insulator.

### Claim 3 (depends on 1)

The motor of claim 1, wherein the insulator includes a slot that is disposed adjacent the guide, and an upper end of the insulator is disposed in the slot.

### Claim 4 (depends on 1)

The motor of claim 1, wherein an upper end of the insulator is in contact with a side surface of the guide.

### Claim 5 (depends on 1)

The motor of claim 1, wherein a length of the guide in an axial direction is greater than a length of a region of an upper end of the insulator that is in contact with an inner circumferential surface of the busbar in an axial direction.

### Claim 6 (depends on 1)

The motor of claim 1, wherein the busbar includes a short protrusion that protrudes from an inner circumferential surface of the busbar to connect a plurality of guides; and
the short protrusion is in contact with an upper surface of the insulator.

### Claim 7 (depends on 1)

The motor of claim 1, wherein a position of the busbar is determined due to an upper surface of the insulator being in contact with a lateral surface of the guide.

### Claim 8 (depends on 1)

The motor of claim 1, wherein the insulator includes:
an outer circumferential part that faces the housing;
an inner circumferential part that faces the rotor; and
an extension part that protrudes from the inner circumferential part toward the busbar, and the extension part is in contact with an inner circumferential surface of the busbar and a lateral surface of the guide.

### Claim 9 (depends on 1)

The motor of claim 1, wherein the extension part and the guide are provided as a plurality of extension parts and a plurality of guides; and the extension parts and the guides are alternately disposed along a circumference of the busbar.
