Abstract
Embodiments relate to a stator unit, a stator, and a motor comprising same, the stator unit comprising: a unit stator core; an insulator disposed on the unit stator core; and a coil wound on the insulator, wherein the unit stator core comprises a main body formed so as to have a prescribed curvature with reference to the centre, and three teeth formed so as to protrude toward the centre from the main body, the main body comprising notches formed between the teeth. Thus mass productivity can be increased as a result of series winding using a coil on a unit stator core having three teeth arranged thereon.
Claims15
A stator unit comprising:
- a unit stator core;
- an insulator disposed on the unit stator core;
- and
- a coil wound around the insulator,
- wherein the unit stator core includes a main body formed to have a predetermined curvature on the basis of a center, and
- three teeth formed to protrude from the main body toward the center,
- wherein the main body includes notches formed between the teeth.
A stator formed by a plurality of stator units disposed along a circumferential direction, each of the stator units comprising:
- a unit stator core;
- an insulator disposed on the unit stator core;
- and
- a coil wound around the insulator,
- wherein the unit stator core includes a main body formed to have a predetermined curvature on the basis of a center, and
- three teeth formed to protrude from the main body toward the center,
- wherein the main body includes notches formed between the teeth.
A motor comprising:
- a rotary shaft;
- a rotor having the rotary shaft disposed at a center thereof;
- a stator disposed at the outside of the rotor;
- a housing configured to accommodate the rotor and the stator;
- and
- a bus bar disposed on the stator,
- wherein the stator is formed by disposing a plurality of stator units along a circumferential direction,
- wherein the stator unit includes a unit stator core,
- an insulator disposed on the unit stator core, and
- a coil wound around the insulator and having an end portion connected to the bus bar,
- wherein the unit stator core includes a main body formed to have a predetermined curvature on the basis of a center, and
- three teeth formed to protrude from the main body toward the center,
- wherein the main body includes notches formed between the teeth.
