AI Technical Summary

Problems solved by technology

This kind of electromagnet has a simple structure, is easy to manufacture, and has good sealing performance; but on the other hand, this kind of electromagnet has poor heat dissipation performance. Therefore, to generate a large holding force, a large holding current must be continuously applied. Not only is power wasted, but the coil overheats, rendering the job useless

Embodiment Construction

[0013] A specific example of the present invention is given below.

[0014] by figure 2 For example, magnetic sleeve 1, magnetic ring 2, moving iron core 3, bottom cover 5, ferromagnetic ring 6, magnetic cover 7, and disc 9 are all made of 10# steel, and the outer diameter of magnetic ring 2 is 82mm. The inner diameter is 70mm, which is divided into two ferromagnetic rings 6; the diameter of the cylindrical iron core of the moving iron core 3 is 45mm, the thickness of the disc 9 is 8mm, and the diameter is 63mm; the effective height of the inner cavity of the electromagnet is 87mm; the diameter of the coil is 0.85mm Copper enameled wire, when the conduction current power is 3W, the holding force reaches 800N.

[0015] by image 3 As an example, the cylindrical iron core of the moving iron core 3 is composed of a steel column with a diameter of 45mm and a height of 25mm and a NdFeB permanent magnet 11 connected together with a diameter of 45mm and a height of 25mm. The NdFeB...

Abstract

This invention puts forward a high-kept column tractive magnet containing a magnetic conduction jacket, a magnetic conduction ring, a moving iron core, a coil and a bottom cover, among which, the conduction ring is divided into N coaxial-connected magnetic rings made of ferromagnetic materials, circle slits are reserved between two adjacent rings, these slits are filled and connected with non-ferromagnetic materials, a round magnetic conduction cover is added onto the column iron core to form a moving core, the cover is composed of N-1 coaxially connecter ring bodies and a disk made of ferromagnetic material, circle slits filed and connected by non-ferromagnetic materials are kept between adjacent ring bodies and disks the disk and the column iron core are connected by magnet or integrated as one.

Description

Technical field: [0001] The invention relates to a traction electromagnet. Background technique: [0002] At present, cylindrical traction electromagnets are used as reciprocating motion power mechanisms in many technical fields, such as figure 1 As shown, the outside of this electromagnet is a magnetic permeable sleeve 1 made of tubular ferromagnetic material, the bottom end of the magnetic permeable sleeve is sealed by a bottom cover 5 made of ferromagnetic material, and the upper end is sealed by a magnetic permeable sleeve made of ferromagnetic material. The ring 2 is sealed, and the tubular coil 4 is placed inside the magnetic sleeve 1. The moving iron core 3 extends into the inside of the coil 4 from the inner hole of the magnetic ring 2. When the power is applied, the end of the moving iron core 3 and the bottom of the magnetic sleeve The cover 5 contacts and generates suction at the contact. This kind of electromagnet has a simple structure, is easy to manufacture,...
