Abstract
A motor includes an enhanced strength of a stator, the stator being formed with a plurality of core plates stacked one on top of another, and a rotor rotatably disposed at an inner side or at an outer side of the stator. Each core plate includes a body provided in a shape of an arc, a plurality of teeth radially extended from the body, and having a coil wound thereto, at least one first slit part formed on the body by being slit in a radial direction of the body, and at least one second slit part formed on the body by being slit in a circumferential direction of the body.
Claims20
A motor comprising:
- a stator formed with a plurality of core plates stacked one on top of another;
- and
- a rotor rotatably disposed at an inner side or at an outer side of the stator,
- wherein each core plate comprises:
- a body provided in a shape of an arc;
- a plurality of teeth radially extended from the body;
- and
- at least one first slit part formed on the body by being slit in a radial direction of the body, and at least one second slit part formed on the body by being slit in a circumferential direction of the body.
A washing machine comprising:
- a body;
- a tub disposed inside the body to store washing water;
- a drum disposed inside the tub while being rotatably supported by the tub through a driving shaft;
- and
- a motor mounted at the tub and configured to rotate the driving shaft, wherein the motor comprises:
- a stator formed with a plurality of core plates stacked one on top of another;
- and
- a rotor rotatably disposed at an inner side or at an outer side of the stator,
- wherein each core plate comprises:
- a body provided in a shape of an arc;
- a plurality of teeth radially extended from the body;
- and a plurality of bending parts formed by slitting at least one portion of the body at positions between teeth adjacent to each other among the plurality of teeth, in a radial direction and in a circumferential direction.
A motor for a washing machine configured to be used to rotate a drum of the washing machine, the motor comprising:
- a stator formed with a plurality of core plates stacked one on top of another;
- and
- a rotor rotatably provided to electromagnetically interact with the stator,
- wherein each core plate comprises:
- a body provided in a shape of an arc;
- a plurality of teeth radially extended from the body;
- at least two first slit parts formed at a portion of the body positioned between teeth, which are adjacent to each other among the plurality of teeth, in a first direction;
- and
- at least one second slit part disposed between the at least two first split parts, and formed by slitting the body in a second direction different from the first direction.
A stator comprising:
- a plurality of core plates stacked one on top of another, wherein each core plate comprises:
- an arc-shaped body;
- a plurality of teeth which extend from the body;
- a first slit part formed in the body in a first direction, between two adjacent teeth;
- a second slit part formed in the body in the first direction, between the two adjacent teeth, and having an opening along a side of the body from which the teeth extend;
- and
- a third slit part formed in the body in a second direction, communicating with the first slit part.
