Abstract
The invention provides a radial anisotropic magnetic ring combination which is composed of an inner magnetic ring and an outer magnetic ring. The inner magnetic ring is of a cylinder shape. The outer magnetic ring is of a square shape, and the interior of the outer magnetic ring is of a cylinder shape. The outer diameter of the inner magnetic ring is the same as the inner diameter of the outer magnetic ring. The outer side of the inner magnetic ring and the inner side of the outer magnetic ring are the same in magnetic polarity. The radial anisotropic magnetic ring combination has the technical advantages that the magnetic rings are combined and used, and therefore effective restraining can be achieved within the wide frequency range; the magnetic rings can be dismantled, and therefore installation is convenient to carry out.
Description
Technical field
the present invention relates to the anisotropy magnet ring combination of a kind of footpath, belong to motor device technical field.
Background technology
magnet ring is anti-interference element conventional in electronic circuit, has good inhibitory action for high-frequency noise, generally uses Ferrite Material (Mn-Zn) to make.Existing magnet ring conventionally separately uses, thus can only in very narrow frequency range, suppress, and also existing magnet ring is generally integral structure, can not be split, and installs cumbersome.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, the anisotropy magnet ring combination of a kind of footpath is provided.
Footpath of the present invention anisotropy magnet ring combination, formed by internal magnetic ring and outer magnetic ring, described internal magnetic ring is cylindrical shape, described outer magnetic ring is square magnetic ring, its inside is cylindrical shape, the external diameter of described internal magnetic ring is identical with the internal diameter of outer magnetic ring, and described internal magnetic ring outside and outer magnetic ring inner side have identical pole polarity.
Described internal magnetic ring is identical with the length of outer magnetic ring.
Described internal magnetic ring is different with the length of outer magnetic ring.
Footpath of the present invention anisotropy magnet ring combination, has following technique effect: being used in combination magnet ring can effectively suppress in very wide frequency range; Magnet ring can split, and installs more convenient.
Brief description of the drawings
Fig. 1 is the sectional view of footpath of the present invention anisotropy magnet ring combination.
Wherein, 1 is internal magnetic ring, and 2 is outer magnetic ring.
Embodiment
As shown in Figure 1, footpath of the present invention anisotropy magnet ring combination, formed by internal magnetic ring 1 and outer magnetic ring 2, described internal magnetic ring 1 is cylindrical shape, described outer magnetic ring 2 is square magnetic ring, its inside is cylindrical shape, and the external diameter of described internal magnetic ring 1 is identical with the internal diameter of outer magnetic ring 2, and described internal magnetic ring 1 outside and outer magnetic ring 2 inner sides have identical pole polarity.Described internal magnetic ring 1 is identical with the length of outer magnetic ring 2.Described internal magnetic ring 1 and the length of outer magnetic ring 2 also can be different.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the invention is not restricted to above-mentioned execution mode, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from aim of the present invention, make a variety of changes.
