Embodiment 1

[0042]It adopts the shape of a quadrangular pyramid, and coils are arranged on each surface, and the magnetic field generated by the coils is perpendicular to the plane. Since the magnetic field generated by each surface coil will generate a large electromagnetic pull, it is necessary to add a support body at the core for support.

[0043] At the same time, due to the winding of wires on each surface, a standard magnetic field and magnetic field intensity need to be formed. Therefore, the wire winding needs to form a solenoid-like winding at a helical angle as much as possible. As shown in the figure, there are formed winding ends perpendicular to the surface and protruding on each surface, and wires are wound on the winding ends, and the wires are helically wound along the direction in which the winding ends protrude. Therefore, based on the support of the winding end, the wire is coiled in a helical shape and energized to form a magnetic field perpendicular to the surface w...

Embodiment 2

[0047] A quadrangular pyramid structure is adopted, the bottom surface is rectangular, and the other four sides are triangular. The preferred range of inclination angle of the triangular surfaces is 40° to 65°.

[0048] A protruding winding end perpendicular to the surface is formed on each surface of the quadrangular pyramid, and a wire is wound on the winding end, and the wire is spirally wound along the protruding direction of the winding end. Therefore, based on the support of the winding end, the wire is coiled in a helical shape and energized to form a magnetic field perpendicular to the surface where the winding end is located.

[0049] like figure 1 and 3 As shown, the magnetic field of the triangular faces converges toward the inside, the rectangle at the bottom is the target face for enhancing the magnetic field, and the inclination angles of the four triangular faces can maximize the magnetic field converging effect.

[0050] Specifically, it also involves the dir...

Embodiment 3

[0054] The Halbach array is an array structure of special-shaped electromagnetic units. Through the special magnetization direction arrangement, the magnetic induction lines of the permanent magnets can be superimposed on one side and offset on the other side, so that the permanent magnets in the array can enhance the unilateral magnetic field, while the other side Weakening the magnetic field on one side, that is, a special structure that can realize the convergence of the magnetic field to increase the density of the magnetic field line on one side.

[0055] The special-shaped electromagnetic units need to be fixed in the array, so an assembly chassis needs to be designed for placement. specific:

[0056] The assembly chassis includes sequentially arranged installation slots, and special-shaped electromagnetic units are assembled in the installation slots. The installation slot includes a slot wall that conflicts with the end faces of the winding ends on the special-shaped ...

Abstract

The invention discloses a special-shaped electromagnetic unit, an array and application. The special-shaped electromagnetic unit comprises supporting bodies and spirally wound wires arranged on the supporting bodies; each supporting body comprises a base surface which can be spliced with the surface on the adjacent supporting body to form a plane, and an edge side surface which is positioned on the same side of the base surface and of which the orthographic projection to the base surface falls into the base surface; winding ends which are perpendicular to the surface and protrude are formed onthe base surfaces and the edge side surfaces; the wires are spirally wound on the winding ends and are electrified to form a magnetic field perpendicular to the surface where the winding ends are located; a magnetic field formed by the electrified coils on the edge side surfaces faces the interiors/exteriors of the supporting bodies, and the effect of enhancing the same magnetic pole direction and the same magnetic pole strength of the magnetic field generated by the electrified coils on the base surfaces is achieved. The electromagnetic unit can enhance the magnetic field above the base surfaces, the enhancement effect is obvious, the amplification is uniform, and the controllability is strong. Moreover, the cost can be controlled according to actual needs, and the preparation is flexible and controllable. In addition, the electromagnetic unit is wide in application range and high in universality.

Description

technical field [0001] The invention relates to the field of electromagnetic technology, in particular to a special-shaped electromagnetic unit, array and application. Background technique [0002] An electromagnet is a device that generates a magnetic field when the coil is energized. Generally, a conductive winding that matches its power is wound outside the iron core. This coil with current is magnetic like a magnet. The iron core is usually made into a bar or hoof shape to make it easier to be magnetized. And in order to make the magnetism disappear after the electromagnet is powered off, the iron core usually adopts a soft magnetic material with faster degaussing. Therefore, the electromagnet exhibits magnetism when energized, and the magnetism disappears when the power is turned off. The electromagnet is widely used in daily life, and the power of the generator has been greatly improved due to its invention. [0003] The characteristics of the electromagnet are main...
