Abstract
A divided core of a motor includes: a stator core comprising a plurality of core segments; a back yoke forming a circumference of the core segments; and teeth extending from the back yoke towards a radial direction of the back yoke, wherein the plurality of the core segments are disposed along an axial direction of the stator core, and there are some areas where the teeth are overlapped with each other when disposing the core segments.
Claims20
A divided core of a motor, the divided core comprising:
- a stator core comprising a plurality of core segments configured to form each phase of 3-phase or single phase power motor that are configured to be arranged along an axial direction of the stator core, each of the plurality of core segments comprising:
- a back yoke that surrounds one of the plurality of core segments, and
- a tooth that extends from an inner circumferential surface of the back yoke along a radial direction of the back yoke,
- wherein the teeth of the plurality of core segments are configured to overlap with one another in the axial direction based on the plurality of core segments being arranged along the axial direction of the stator core.

A divided core of a motor, the divided core comprising:
- a stator core comprising a plurality of core segments that are configured to be stacked on one another in an axial direction of the stator core, each of the plurality of core segments comprising:
- a back yoke that surrounds one of the plurality of core segments,
- a tooth that extends from an inner circumferential surface of the back yoke along a radial direction of the back yoke and that protrudes from the back yoke in the axial direction of the stator core,
- an insulator that surrounds the tooth, and
- coils that are wound around the insulator, wherein the insulator is configured to insulate the tooth from the coils,
- wherein a height of the tooth is greater than a height of the back yoke in the axial direction, and
- wherein the insulator comprises a bent portion that is bent along the inner circumferential surface of the back yoke.
