Abstract
The present invention relates to a kind of magnet ring, more particularly to a kind of magnet ring for adding magnetic material.A kind of magnet ring, including the magnet ring circle with a predetermined amount formed by magnetic core material sintering, the magnetic material of the setting of addition first magnetic resistance on the inside of the magnet ring circle, the magnetic material of the setting of addition second magnetic resistance on the outside of the magnet ring circle, the second setting magnetic resistance is less than the described first setting magnetic resistance, the magnetic resistance of the magnetic material added between on the inside of the magnet ring circle and on the outside of the magnet ring circle is between the described first setting magnetic resistance and the second setting magnetic resistance so that the magnetic resistance of each circle is equal in magnet ring circle.The present invention provides a kind of magnet ring for progressively adding the less magnetic material of magnetic resistance on the inside of the magnet ring circle to outside, can balance the magnetic resistance of whole magnet ring magnetic circuit so that magnet ring inner side and outer side magnetic resistance realizes balancing magnetic force line distribution situation close to equal.
Description
Technical field
The present invention relates to a kind of magnet ring, more particularly to a kind of magnet ring for adding magnetic material.
Background technology
The magnet ring occurred currently on the market, its magnetic core are substantially formed by single uniform magnetic core material compacting sintering,
Such material-structure is simple and easily fabricated, but since the inner ring girth of magnet ring differs bigger with outer shroud girth, causes
Small outside is big on the inside of magnetic resistance, magnetic line of force skewness.
The content of the invention
For the above problem existing for current magnet ring, the present invention provides a kind of magnet ring.
The technical proposal for solving the technical problem of the invention is：
A kind of magnet ring, including magnet ring circle forming and with a predetermined amount, the magnet ring circle are sintered by magnetic core material
The magnetic material of inner side addition the first setting magnetic resistance, the magnetic material of magnet ring circle outside addition the second setting magnetic resistance are described
Second setting magnetic resistance is less than the described first setting magnetic resistance, the magnetism added on the inside of the magnet ring circle between magnet ring circle outside
The magnetic resistance of material is between the described first setting magnetic resistance and the second setting magnetic resistance so that the magnetic resistance of each circle in magnet ring circle
It is equal.
Preferably, the magnetic resistance of the magnetic material of addition is less than on the inside of the magnet ring circle on the outside of the magnet ring circle
The magnetic resistance of the magnetic material added in magnetic material.
Preferably, the magnet ring circle is circular magnet ring circle.
Preferably, the magnetic material added is the stepping composite magnetic of magnetic resistance.
Preferably, the chassis of the magnet ring circle is in Archimedes spiral type.
Preferably, the magnet ring circle is an integral molding structure.
Preferably, the through hole of the magnet ring circle is the concentric circles not waited.
Beneficial effects of the present invention：The present invention provides one kind and the less magnetic of magnetic resistance is progressively added to outside on the inside of magnet ring circle
Property material magnet ring, the magnetic resistance of whole magnet ring magnetic circuit can be balanced so that magnet ring inner side and outer side magnetic resistance is realized flat close to equal
Weigh magnetic line of force distribution situation.
Brief description of the drawings
Fig. 1 is the structure diagram of the magnet ring of the present invention.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as limiting to the invention.
Magnet ring as shown in Figure 1, including magnet ring circle 1 forming and with a predetermined amount, magnetic are sintered by magnetic core material
The magnetic material of 3 addition the first setting magnetic resistance on the inside of ring, the magnetic material of 2 addition the second setting magnetic resistance of magnet ring circle outside, the
Two setting magnetic resistance are less than the first setting magnetic resistance, and the magnetic resistance of the magnetic material added on the inside of magnet ring circle between 3 and magnet ring circle outside 2 is situated between
Between the first setting magnetic resistance and the second setting magnetic resistance so that the magnetic resistance of each circle is equal in magnet ring circle 1.
The magnet ring circle of predetermined amount, namely magnet ring circle the number of turns can depending on application demand,.Using the present embodiment system
Into magnet ring circle, the magnetic resistance of obtained each circle is all equal, and the magnetic resistance of each circle is equal, with regard to that can obtain the uniform magnetic of the magnetic line of force
Ring.
The preferred embodiment of the present invention, the magnetic resistance of the magnetic material of 2 additions is less than close to magnet ring on the outside of magnet ring circle
The magnetic resistance of the magnetic material added in the magnetic material of circle inner side 3, so as to balance the magnetic resistance of whole magnet ring magnetic circuit, realizes equilibrium
The magnetic line of force is distributed.
That is, on the inside of magnet ring circle 3 additions be magnetic resistance maximum magnetic material, 2 add is magnetic on the outside of magnet ring circle
Hinder minimum magnetic material.Preferably, which is soft magnetic materials.
The preferred embodiment of the present invention, magnet ring circle 1 are circular magnet ring circle 1.
The preferred embodiment of the present invention, the magnetic material added are the stepping composite magnetic of magnetic resistance.
The preferred embodiment of the present invention, the chassis of magnet ring circle 1 is in Archimedes spiral type.
The preferred embodiment of the present invention, magnet ring circle 1 are an integral molding structure.
Integrally formed structure causes the precision higher of magnet ring circle 1.
The preferred embodiment of the present invention, the through hole of magnet ring circle 1 are the concentric circles not waited.
The foregoing is merely preferred embodiments of the present invention, not thereby limit embodiments of the present invention and protection model
Enclose, to those skilled in the art, should can appreciate that and all be made with description of the invention and diagramatic content
Equivalent substitution and obviously change obtained scheme, should be included in protection scope of the present invention.
