Abstract
The present invention discloses a stator of a motor including a circular stator core formed by stacking a plurality of sheets, a plurality of bobbins fixed to the inner circumferential surface of the stator core at predetermined intervals and rotatably connected to each other, and stator coils wound around the outer circumferential surfaces of the bobbins to be connected to each other, and a method for manufacturing the same. The stator of the motor can reduce an assembly time by omitting a process for wiring the stator coils, and also reduce a number of components and manufacturing expenses by omitting a wiring PCB.
Claims7
A stator of a motor, comprising:
- a stator core provided by stacking a plurality of sheets;
- a plurality of bobbins fixed to an inner circumferential surface of the stator core at predetermined intervals, each bobbin having a connection portion to rotatably connect the bobbins to each other, and a coil winding unit around which the stator coil is wound,
- wherein the connection portions comprise:
- hinge connectors units having support units,
- wherein the support units have radially outer rear surfaces, and hinge grooves and hinge protrusions provided on opposing ends of respective support units, and
- wherein the hinge connection units rotatably connect the bobbins to each other such that end surfaces of the hinge grooves are configured to abut respective radially outer rear surfaces of the support units, when the bobbins are connected and arranged in a generally straight line;
- and
- stator coils wound around the outer circumferential surfaces of the bobbins such that the stator coils are connected to each other.
