Abstract
A stator for a motor, the stator including a plurality of busbars, in which the plurality of busbars includes a first busbar, a second busbar, and a third busbar, two opposite ends of the first busbar are spaced apart from each other in a circumferential direction C and a radial direction R, two opposite ends of the second busbar are spaced apart from each other in the circumferential direction C and an axial direction A, and two opposite ends of the third busbar are spaced apart from each other in the circumferential direction C, the radial direction R, and the axial direction A.
Claims17
A stator for a motor, the stator comprising:
- a plurality of assemblies arranged in a circumferential direction C of the stator;
- and
- a hole provided at a center of the plurality of assemblies,
- wherein each of the plurality of assemblies comprises:
- a stator core;
- a bobbin configured to surround an outer surface of the stator core;
- a coil wound around the bobbin multiple times and having incoming and outgoing lines respectively provided at two opposite ends thereof;
- and
- a plurality of busbars disposed on the bobbin,
- wherein the plurality of busbars comprises a first busbar, a second busbar, and a third busbar,
- wherein two opposite ends of the first busbar in a circumferential direction C of the first bus bar are spaced apart from each other in the circumferential direction C and a radial direction R of the stator,
- wherein two opposite ends of the second busbar in a circumferential direction C of the second bus bar are spaced apart from each other in the circumferential direction C and an axial direction A of the stator, and
- wherein two opposite ends of the third busbar in a circumferential direction C of the third busbar are spaced apart from each other in the circumferential direction C, the radial direction R, and the axial direction A of the stator,
- wherein the third busbar has a shape bent primarily in a direction inclined with respect to the radial direction R and the circumferential direction C of the stator, bent secondarily in the circumferential direction C of the stator, bent tertiarily in a direction inclined with respect to the axial direction A and the circumferential direction C of the stator, and then bent quaternarily in the circumferential direction C of the stator while extending from one end B3-1 of the third busbar toward the other end B3-2 of the third busbar,
- wherein one end B1-1 of the first busbar in the circumferential direction C of the first bus bar and one end B2-1 of the two opposite ends of the second busbar in the circumferential direction C of the second busbar, which is disposed adjacent to the one end B1-1 of the first busbar, are disposed at a first height H1 in the axial direction A, and
- wherein the one end B3-1 of the two opposite ends of the third busbar in the circumferential direction C of the third busbar, which is disposed adjacent to the one end B1-1 of the first busbar and the one end B2-1 of the second busbar, is disposed at a second height H2 different from the first height H1 in the axial direction A.
