AI Technical Summary

Problems solved by technology

In the current electromagnet structure, the conduit and the armature are connected by surface contact. When the armature moves in the conduit, the friction force generated is relatively large, and the resulting force hysteresis is also relatively large, which affects the accuracy of the product.

Embodiment Construction

[0020] In conjunction with the accompanying drawings, the present invention is described in detail, but the scope of protection of the present invention is not limited to the following examples, that is, all simple equivalent changes and modifications made with the patent scope of the present invention and the content of the specification are still patents of the present invention. covered.

[0021] Such as Figure 1-4 As shown, an electromagnet buckle structure includes an armature 1, a conduit 2 sleeved outside the armature and made of a magnetically conductive material, and one end of the conduit is provided with a ring-shaped non-magnetically conductive material along its circumference. The formed magnetic isolation ring 3 is provided with several convex points 4 at intervals on the inner surface of the conduit, and the several convex points form a buckle structure, so that the friction between the conduit and the armature changes from surface friction to point friction. ...

Abstract

The invention discloses a buckle point structure of an electromagnet, which comprises an armature and a guide pipe made of magnetic conducting material and sleeved outside the armature, wherein a ring-shaped magnetism isolating ring made of non-magnetic conducting material is arranged at one end of the guide pipe in the circumferential direction; and a plurality of convex points are arranged on the inner side of the guide pipe at intervals to form the buckle point structure through which surface friction between the guide pipe and the armature changes into point friction, and accordingly the friction force is reduced, the magnetic hysteresis of the product is reduced, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to an electromagnet, in particular to an electromagnet buckle structure. Background technique [0002] Because the electromagnet needs to input different currents, it can output different magnitudes of force, so that the armature stays in different positions, and realizes precise control of the flow rate of the valve body, so as to meet the requirements of different customers for the use of the product. But some main parameters such as the size of the magnetic hysteresis and the size of the force hysteresis loop will affect the value of the electromagnet in practical applications. In the current electromagnet structure, the conduit and the armature are connected by surface contact. When the armature moves in the conduit, the frictional force generated is relatively large, and the resulting force hysteresis is also relatively large, thereby affecting the accuracy of the product. How to make the product more effectively meet the re...
