Embodiment 1

[0013] Embodiment one: see attached figure 1 shown.

[0014] A short-column silicon steel sheet, which is in the shape of a "day", includes two side columns 1, a central column 2 and two connecting pieces 3, the two side columns 1 and the central column 2 are arranged side by side, and the two side columns 1 are respectively Located on both sides of the axis of the central column 2 , two connecting pieces 3 are respectively connected to the ends of the same side of the side column 1 and the central column 2 . Usually, the short-column silicon steel sheet can be formed by splicing multiple pieces. For example, in this embodiment, the silicon steel sheet is formed by splicing E sheet 4 and I sheet 5, wherein two side columns 1, center column 2 and one connecting sheet 3 form E sheet 4, and another connecting sheet 3 forms I slice 5.

[0015] Since the central column 2 and the side column 1 are arranged side by side between two connecting pieces 3 arranged in parallel, the len...

Abstract

The invention relates to a short-column silicon steel sheet. The short-column silicon steel sheet comprises two side columns, a middle column and two connecting pieces which form a shape of a Chinese character 'ri', wherein the two side columns and the middle column are arranged in parallel, the two side columns are respectively located on two sides of the axis of the middle column, and the two connecting pieces are respectively connected to the same-side ends of the side columns and the same end of the middle column. The height of the middle column is smaller than that of each side column, so that air gaps are formed between the end of the middle column and the connecting pieces. An iron core composed of the short-column silicon steel sheets is formed by stacking a plurality of short-column silicon steel sheets. The air gaps are formed between the middle column and the connecting pieces of the short-column silicon steel sheet and the iron core so that the magnetic resistance can be improved and magnetic leakage and electromagnetic interference can be reduced.

Description

technical field [0001] The invention relates to a silicon steel sheet and an iron core made of the silicon steel sheet. Background technique [0002] The silicon steel sheet is the main component of the iron core. Existing silicon steel sheets are generally in the form of a sun-shaped integrated structure or a multi-piece spliced ​​structure. Among them, there are three parallel sheet-shaped parts, called side columns and central columns, which are connected between the other two parallel sheet-shaped parts so that they are in between the two parallel sheet-shaped parts. The lengths between them, that is, their heights are equal. The iron core made of this silicon steel sheet is prone to magnetic saturation during work. Contents of the invention [0003] The object of the present invention is to provide a short-pillar silicon steel sheet that avoids magnetic saturation and an iron core using the short-pillar silicon steel sheet. [0004] In order to achieve the above o...
