Abstract

A motor includes a shaft, a rotor disposed at the shaft, a stator disposed on an outer side of the rotor, a busbar disposed on the stator, a housing accommodating the rotor, the stator, and the busbar, and having an opening formed on one side thereof, and a bracket disposed on a side of the opening of the housing. The busbar includes a busbar body, a reinforcing rib disposed to protrude from an upper surface of the busbar body, and a weight groove formed in a lower surface of the busbar body.

First claim

What is claimed is:

1. A motor comprising:
a shaft;
a rotor provided at the shaft;
a stator provided at an outer side of the rotor;
a busbar provided on the stator;
a housing configured to accommodate the rotor, the stator, and the busbar, and having an opening formed at one side thereof; and
a bracket provided on a side of the opening of the housing,
a lead wire unit disposed at an end of a coil of the stator,
wherein the busbar includes:
a busbar body;
a fixing guide disposed to protrude from one side of the busbar body;
a reinforcing rib protruding from a surface of the busbar body facing the bracket; and
a weight groove formed in a surface of the busbar body facing the stator,

wherein the lead wire unit comprises a lead wire, a clamp disposed on one side of the lead wire, and a connection terminal disposed on the other side of the lead wire,
wherein the fixing guide is coupled to the coil of the stator so that the end of the coil is exposed, and
wherein the clamp is disposed at the exposed end of the coil coupled to the fixing guide.

2. The motor of claim 1 , wherein the busbar further includes an add rib formed in the weight groove.

3. The motor of claim 1 , further comprising a terminal assembly coupled to the connection terminal.

4. The motor of claim 3 , wherein the reinforcing rib is provided on a side of the coil coupled to the lead wire with respect to a virtual line passing through a center of the busbar body.

5. The motor of claim 1 , wherein the fixing guide is formed in a hook shape and is provided on an outer circumferential surface of the coil.

6. The motor of claim 5 , wherein the fixing guide is formed of a metallic material and is fused with the coil.

7. The motor of claim 6 , wherein the fixing guide is provided between the stator and a terminal arranged at the busbar body.

8. A motor comprising:
a shaft;
a rotor provided at the shaft;
a stator provided at an outer side of the rotor;
a busbar provided on the stator;
a housing configured to accommodate the rotor, the stator, and the busbar, and having an opening formed at one side thereof; and
a bracket provided on a side of the opening of the housing,
wherein the busbar includes:
a busbar body; and
a fixing guide protruding from one side of the busbar body,
wherein the fixing guide is coupled to a coil of the stator so that an end of the coil is exposed,
wherein a lead wire unit is disposed at the exposed end of the coil coupled to the fixing guide, and
wherein the lead wire unit comprises a lead wire, a clamp disposed on one side of the lead wire, and a connection terminal disposed on the other side of the lead wire.

9. The motor of claim 8 , wherein the fixing guide is formed in a hook shape and provided on an outer circumferential surface of the coil.

10. The motor of claim 9 , wherein the fixing guide is formed of a metallic material and is fused with the coil.

11. The motor of claim 10 , wherein the fixing guide is provided at a level lower than that of a terminal arranged at the busbar body.

12. The motor of claim 8 , further comprising a terminal assembly coupled to the connection terminal.
