Abstract
The utility model discloses an integral soft magnetic alloy iron-core formed from the bonding of insulation soft magnetic alloy iron power particles. The insulation soft magnetic alloy iron power particles can be nickel-iron alloy particles, iron-silicon-aluminum alloy particles, or nickel-iron-molybdenum alloy particles. The surface of the insulation soft magnetic alloy particle is provided with an insulation resin layer. The soft magnetic alloy iron core of the utility model is compared with a traditional used iron core, the magnetic leakage of the soft magnetic alloy iron core is greatly reduced, and vibration and noise can not appear, and energy loss is efficiently reduced. The soft magnetic alloy iron core of the utility model can be bonded into various three-dimensional entities due to the three-dimensional flow direction ability of the magnetism of the soft magnetic alloy iron power particles to satisfy iron cores required by various magnetic flow directions.
Description
Technical field
The utility model relates to the soft magnetic alloy core of using in various electric, the electronic equipments.
Background technology
Its structure of iron core of traditional transformer, electric energy meter etc. is generally that the ferroalloy sheet is stacked to be fixed together, and is coated with on each ferroalloy sheet and is useful on the insulating coating that prevents electric current circulation between lamination, to reduce eddy current loss.Its weak point is that ferroalloy lamella leakage field between layer is serious, and in working order down, the ferroalloy synusia is easy to generate vibrations, noise and energy loss occur, in addition, the ferroalloy sheet also has a sizable defective, is exactly that its magnetic characteristic is very strong on the lamination plane, but very weak on other direction, adopt the stacked fixing core of ferroalloy sheet, the shape in its space is configured with very big limitation, is subject to many limitations, thereby causes the restriction of iron core flow direction.
The utility model content
The utility model provides a kind of soft magnetic alloy core, and this soft magnetic alloy core can effectively reduce energy loss, avoids occurring vibrations and noise, and its shape structure can be made into various 3D solids as required.
To achieve these goals, the technical solution adopted in the utility model is: a kind of soft magnetic alloy core, it is characterized in that: the integrated soft magnetic alloy core of described soft magnetic alloy core, this integrated soft magnetic alloy core is formed by insulation magnetically soft alloy ferrous powder granules bonding.
As a kind of preferred version of the present utility model, described insulation magnetically soft alloy ferrous powder granules can be dilval particle, sendust particle or ferronickel molybdenum alloy particle.
As a kind of preferred version of the present utility model, described insulation magnetically soft alloy ferrous powder granules insulation mode is for to establish insulating resin layer on magnetically soft alloy ferrous powder granules surface.
The utility model is owing to adopt technique scheme, the structure of iron core is changed into integral structure by laminated construction, its leakage field reduces greatly, vibrations and noise can not appear, effectively reduce energy loss, and because the three-dimensional flow of magnetically soft alloy ferrous powder granules magnetic to ability, can be bonded to it various 3D solids, to satisfy the iron core of various flow direction requirements.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a kind of soft magnetic alloy core structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is another kind of soft magnetic alloy core structural representation;
Fig. 4 is the vertical view of Fig. 3.
Embodiment
As depicted in figs. 1 and 2; be soft magnetic alloy core embodiment one of the present utility model; its structure integrated soft magnetic alloy core 1 that insulation magnetically soft alloy ferrous powder granules bonding forms of serving as reasons, described insulation magnetically soft alloy ferrous powder granules can be dilval particle, sendust particle or ferronickel molybdenum alloy particle.Be provided with insulating resin layer on described insulation magnetically soft alloy ferrous powder granules surface.
As Fig. 3 and Fig. 4, be another magnetically soft alloy kind iron core of the utility model embodiment, these magnetically soft alloy kind iron core 2 architectural characteristics are identical with embodiment one, just the 3D shape difference of soft magnetic alloy core.
Its three-dimensionally shaped making of soft magnetic alloy core of the present utility model is very simple, only need a simple solidification process in the P/M of routine compression back, curing temperature and time are decided by employed resin, be generally under 150 degrees centigrade of temperature, to keep and got final product in one hour, subsequently under air 300-500 degree centigrade, heat-treat again,, strengthen the performance that shows under the intermediate frequency with further minimizing current loss, the high-performance low-density, characteristics such as hypotonicity.
The structure of the utility model soft magnetic alloy core is changed into integral structure by laminated construction, its leakage field reduces greatly, vibrations and noise can not appear, effectively reduce energy loss, and because the three-dimensional flow of magnetically soft alloy ferrous powder granules magnetic to ability, can be bonded to it various 3D solids, to satisfy the soft magnetic alloy core of various flow direction requirements, as be applied to the intrasystem iron core of ignition transformer, the iron core in the electric current of electric energy meter, voltage iron core and the motor etc.
