The iron core products produced by our company are divided into two categories. The iron core of the axial motor and the iron core of the ignition coil are generally made of Silicon steel sheets. His core part is the effect in the Transformer. The iron core used can be divided into four major categories. Make a summary here to facilitate everyone to collect information in time, do an understanding.
1, three-dimensional and facial
The three-dimensional heart column and iron yoke are not in a plane, and they are radiative, involute, and symmetric. Because the flux distribution is relatively uniform, loss can be reduced; The planar heart column and the iron yoke are in the same plane, with high mechanical strength and good craftsmanship.
2, stack iron core and roll iron core
Generally, they are stacked iron cores, which are stacked by iron cores. There are more forms of rolling iron cores. The air gap between the core of the involute core and the iron yoke is large, affecting the empty current, so the capacity can not be done too small; However, due to the vertical leakage of magnetic flux into the plane of the iron chip, which affects additional losses, the width of the sheet should not be too large, that is, the capacity can not be too large.
3, shell type and core type iron core
The part of the winding in the core of the iron core is called the "heart column", and the part that does not bind the winding only plays a magnetic role is called the "iron yoke." Where the iron core surrounds the winding, it is called shell type; Where the winding surrounds the core column, it is called a core type. The shell type and the core type have their own characteristics, but the transformer manufacturing process determined by the iron core is very different. Once a certain structure is selected, it is difficult to turn into a structure. Most of the transformer cores in our country adopt the superposition core type.
4, single phase and three-phase iron core
The single phase iron core has a single two-column superposition iron core. There are five kinds of single phase single column yoke four-column core, single phase double pillar core, and single phase radiation core; There are four new three-phase column supercharged iron cores, three-phase conjugate five-pillar iron cores, three-phase double-frame supercharged iron cores, and three-phase electric reactor supercharged iron cores.
