Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] refer to figure 1 , the multi-stage air-gap magnetic assembly of the present invention includes a first magnetic core 1 and a second magnetic core 3, and the first magnetic core 1 and the second magnetic core 3 are in principle of the same material, shape and size The magnetic cores are arranged symmetrically, and the left and right end sides are respectively butted with each other, and the central columns are opposite. Between the central column of the first magnetic core 1 and the central column of the second magnetic core 3, there are several central column magnetic spacers 2 stacked up and down, and the central column magnetic spacers 2 of each layer adopt a flexible assembly method, both It can be assembled equidistantly or not equidistantly. The shape and size of the center column magnetic spacer 2 are the same as those of the ce...

Abstract

The invention relates to a magnetic component, and specifically relates to a multi-segment air gap type magnetic component. The multi-segment air gap type magnetic component comprises a first magneticcore and a second magnetic core, wherein the first magnetic core and the second magnetic core are symmetrically arranged, the left ends and the right ends of the first magnetic core and the second magnetic core are in butt joint with each other respectively, and central posts of the first magnetic core and the second magnetic core are opposite; a plurality of central post magnetic gaskets laminated vertically are assembled between the central post of the first magnetic core and the central post of the second magnetic core; and air gaps are formed between the central post of the first magneticcore and the central post magnetic gasket on the topmost layer, between the central post of the second magnetic core and the central post magnetic gasket on the bottommost layer and among the centralpost magnetic gaskets. Compared with a traditional magnetic component, the loss of leakage flux can be reduced and dispersed effectively, and the diffusion flux is reduced, so that the operating temperature of the magnetic component is reduced, and the operating efficiency of the magnetic component is promoted.

Description

technical field [0001] The invention relates to a magnetic assembly, in particular to a multi-segment air-gap magnetic assembly. Background technique [0002] At present, soft ferrite materials mainly include two categories: high-conductivity magnetic components and power magnetic components. According to the specific application fields and environmental requirements of the product, high-conductivity magnetic components can be divided into wide temperature type, wide frequency type, high DC superposition type and anti-EMI and other types; power type magnetic components can be further divided into wide temperature type and low loss, etc. Types of. In terms of shape and size, high-conductivity magnetic components are smaller in size and relatively simple in shape, such as common ring and U-shaped products; power-type magnetic components are larger in size and more complicated in shape, such as common PQ type and PM type. , RM type and other products. In terms of specific ap...
