Embodiment Construction

[0037] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] figure 1 is a detailed view of a core provided in a stator according to the invention, figure 2 is a detailed view showing a stator according to the invention.

[0039] Such as figure 1 with figure 2 As shown, the stator 50 of the present invention includes an annular core 51 and at least one coil 55 wound on the annular core.

[0040] The core 51 is formed of a plurality of core plates 52 which are cut thin metal sheets and processed into a ring shape, stacked on each other in at least two layers in the thickness direction Y.

[0041] On the inner side of each core plate constituting the core 51, a plurality of protruding portions 52a are provided at regular intervals on the circumference of the core 51, each protruding portion 52a extending a predetermined length toward the inner peripheral direction. According to this configura...

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.

Description

technical field [0001] The present invention relates to a stator and a motor having the stator, and more particularly, to a stator and a motor having the stator, wherein the bending process of the core is reduced due to the The number is simplified, reducing manufacturing cost and time, thereby increasing productivity. Background technique [0002] In general, an electric motor (hereinafter referred to as "motor") is a device for converting electrical energy into mechanical energy. Depending on the type of power source, starting method, type of rotor, and type of external structure such as frame and bracket, motors can be classified into many different types. Motors can also be subdivided according to insulation method, bearing type, output power, rotational speed, supply voltage or frequency. [0003] These kaleidoscopic motors are broadly classified as DC motors or AC motors according to the type of power applied to the motors. In addition, direc...
