Abstract

Disclosed is a motor, the motor according to an exemplary embodiment of the present disclosure including a motor housing, a stator mounted inside the motor housing and including a stator core and a coil wound on the stator core, a rotor rotatably installed at a center of the stator, and a busbar provided with a plurality of circumferentially and straightly protruded busbar terminals mounted at an upper surface of the stator, and connected by a coil.

First claim

What is claimed is:

1. A motor, the motor comprising:
a motor housing;
a stator mounted inside the motor housing and including a stator core and a coil wound on the stator core;
a rotor rotatably installed at a center of the stator;
a busbar disposed at an upper side of the stator and including a plurality of circumferentially and straightly protruded busbar terminals; and
a hook groove formed on each of the busbar terminals and accommodating at least a portion of the coil,
wherein the hook groove is downwardly recessed from an upper surface of each of the plurality of busbar terminals.

2. The motor of claim 1 , wherein the busbar includes a busbar body formed with resin, and each of the busbar terminals is protruded from the busbar body in a circumferential direction.

3. The motor of claim 2 , wherein a cross-section of each of the busbar terminals takes a shape of a rectangle.

4. A motor, the motor comprising:
a motor housing;
a stator mounted inside the motor housing and including a stator core and a coil wound on the stator core;
a rotor rotatably installed at a center of the stator;
a busbar disposed at an upper side of the stator and including a plurality of circumferentially and straightly protruded busbar terminals;
a hook groove formed on each of the busbar terminals and accommodating at least a portion of the coil,
wherein the hook groove is downwardly recessed from an upper surface of each of the busbar terminals;
a through hole formed on each of the busbar terminals and having a shape corresponding to that of a periphery of the coil, and
a slit disposed between the through hole and a side end of each of the busbar terminals,
wherein the coil is inserted into the through hole through the slit from the side end of each of the busbar terminals, and
wherein a width of the slit decreases from the side end of each of the busbar terminals to the through hole, and a width of at least a portion of the slit is smaller than that of a diameter of the through hole.

5. The motor of claim 4 , wherein the slit is formed with a bottleneck section connected to the through hole and the side end of each of the busbar terminals.

6. The motor of claim 2 , wherein a body of the busbar is formed with a resin material to be insert injection molded along with the busbar terminals.

7. The motor of claim 2 , wherein each of the busbar terminals is formed in one body with a circularly bent terminal body having a diameter corresponding to that of the body after press-work of a plate member, and each of the busbar terminals is at least twice bent on the terminal body to allow a distal end extending in a circumferential direction of the body.

8. The motor of claim 2 , wherein each of the busbar terminals includes a fusing unit formed with a conductive member at an area contacting the coil.

9. The motor of claim 2 , wherein the busbar includes a first busbar body and a second busbar body, and the busbar terminals of the first busbar body has a first height and the busbar terminals of the second busbar body has a second height.
