Abstract
The present invention provides a stator including a core having a plurality of core plates piled on one another, and a plurality of teeth formed in a regular interval on the circumference of the core. The stator also has a plurality of protuberant parts bent upward from outside to inside on one of the plurality of core plates. The stator further has at least one coil having winding parts wound on the teeth of the core and connecting parts hitched on the protuberant parts. The present invention allows simpler bending process of the core, with fewer molds, thus reducing the manufacture cost and the manufacture time to enhance productivity.
Claims14
A stator comprising:
- a core having a plurality of core plates piled up in a thickness direction on one another;
- a plurality of teeth each extended in a regular interval from the inner circumferential surface of the core;
- a plurality of protuberant parts bent upward from outside to inside of the outer circumference of one of the plurality of core plates;
- and
- at least one coil having winding parts wound on the teeth of the core and connecting parts hitched on the protuberant parts disposed between the teeth to connect the winding parts of the coil.
An electric motor comprising:
- a stator having a core having a plurality of core plates piled up in a thickness direction on one another, a plurality of teeth each extended in a regular interval from the inner circumference of the core, a plurality of protuberant parts bent from outside to inside on one outer circumference of the plurality of core plates, and at least one coil having winding parts each wound on the teeth of the core and connecting parts hitched on the protuberant parts disposed between the teeth to connect the winding parts of the coil;
- a rotor having a magnet in the inner side facing the core;
- and
- a shaft part rotatably provided between the stator and the rotor about the stator.
