Description
Technical field
The utility model is a kind of samarium cobalt permanent magnet body, more particularly to a kind of high-precision motor samarium cobalt permanent magnet body.
Background technology
Magnet steel in the prior art, it is complicated, when magnet exceeds corresponding temperature, continues to use, lead to zero
The damage of part influences normally to operate.Cause using effect bad, leads to the reduction of its service life.
Chinese patent 201020150678.5, discloses a kind of magnet, more particularly to one kind be mainly used for microwave communication techniques,
The samarium-cobalt magnet with cambered surface of audio-visual technology, electrical engineering etc..Including magnet, the magnet includes contour body and rectangular
Body, the contour body and square body are integration, are equipped with middle layer in the magnet, middle layer is coated with nickel coating.
This structure is relative complex, and using effect is relatively bad.
Invention content
The utility model mainly solves the deficiencies in the prior art, compact-sized, further promotes performance,
The temperature that magnet can be paid close attention to constantly enables the high-precision motor samarium cobalt permanent magnet body of its equipment normal operation.
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：
One end of a kind of high-precision motor samarium cobalt permanent magnet body, including magnet steel, the magnet steel is equipped with and magnet body
In integration distribution crozier, the outer wall of the magnet steel, the inner wall of magnet steel, crozier lateral wall respectively be in it is parallel
Distribution, the width of the crozier are more than the width of magnet steel, the inner wall of the crozier and the inner wall of magnet steel, hook-shaped
The outer wall of body and the outer wall of magnet steel are in arc transition respectively, and the magnet steel is made of samarium-cobalt material mold press process
Permanent magnet；
This structure is in motor, further enhancing assembly precision, more matching nonstandard product.
The surface of the magnet steel is equipped with silicon dioxide layer, and the thickness of the silicon dioxide layer is 2um~2.5um,
Embedded foil temperature sensor is equipped in the crozier；
It is described magnet steel be equipped with built-in iron core.
The specific stronger acid resistance of silicon dioxide layer, reduces the corrosivity of product.Iron core can further increase permanent magnet
Magnetism, so that permanent magnet is played best performance.
Preferably, the radius of the crozier inner wall is less than the radius of crozier outer wall.
Preferably, the magnet steel is in a strip shape, and the inclined distribution of the magnet steel, the section that inclines of the magnet steel
Angle is 45 degree~60 degree.
Foil temperature sensor：For sheet type, small volume is embedded in crozier, does not interfere with the usability of magnetic pole
Effectively sensing apparatus temperature change it can in time can alarm, further decrease unnecessary when temperature is more than critical value
Loss ensures production efficiency.
It is brittle by samarium-cobalt magnet, silicon dioxide layer is used in magnet surface, on the one hand protects the magnetism of magnet steel, on the other hand
So that product is extended product service life in acidic environment, protects product to greatest extent.
Resin enamelled coating also has certain barrier propterty, while having both color classification.
Therefore, high-precision motor provided by the utility model samarium cobalt permanent magnet body, further lift structure assembly precision is high,
Properties of product are promoted, are prolonged the service life.

The lateral wall of shape body 2 is in parallelly distribute on respectively, and the width of the crozier 2 is more than the width of magnet steel 1, the crozier
2 inner wall is in arc transition, the magnet steel respectively with the inner wall of magnet steel 1, the outer wall of crozier 2 and the outer wall of magnet steel 1
Body 1 is permanent magnet made of samarium-cobalt material mold press process；
The surface of the magnet steel 1 is equipped with silicon dioxide layer 3, the thickness of the silicon dioxide layer 3 be 2um~
2.5um is equipped with Embedded foil temperature sensor 4 in the crozier 2；
It is described magnet steel 1 be equipped with built-in iron core 5.
The radius of 2 inner wall of crozier is less than the radius of 2 outer wall of crozier.
The magnet steel 1 is in a strip shape, the 1 inclined distribution of magnet steel, and section's angle of inclining of the magnet steel 1 is
45 degree~60 degree.
