Abstract
The utility model is a kind of samarium cobalt permanent magnet body, in particular to a kind of waist drum samarium-cobalt magnet for motor.Including magnet steel, the magnet steel includes torus and prismatoid, and the top of the torus is equipped with the prismatoid with torus in integrated distribution.The further lift structure assembly precision of waist drum samarium-cobalt magnet for motor is high, promotes properties of product, prolongs the service life.
Description
Technical field
The utility model is a kind of samarium cobalt permanent magnet body, in particular to a kind of waist drum samarium-cobalt magnet for motor.
Background technique
Magnet steel in the prior art, structure is complicated, when magnet exceeds corresponding temperature, continues to using leading 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, in particular 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.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, compact-sized, further promotes service performance,
The temperature that magnet can be paid close attention to constantly, the waist drum samarium-cobalt magnet for motor for enabling its equipment to operate normally.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of waist drum samarium-cobalt magnet for motor, including magnet steel, the magnet steel include torus and prismatoid,
The top of the torus is equipped with the prismatoid with torus in integrated distribution；
The upper end of the torus is equipped with upper surface, and the upper surface stretches in the bottom surface of prismatoid, described
The base length of prismatoid be greater than the length of upper surface, the bottom end of the torus is equipped with lower end surface, the lower end
The length in face is greater than the length of upper surface, and the length of the upper surface is greater than the base length of prismatoid；
This structure is to further enhance assembly precision in motor, more matching nonstandard product.
The surface of the magnet steel is equipped with silicon dioxide layer, the silicon dioxide layer with a thickness of 2um~2.5um,
Embedded foil temperature sensor is equipped in the magnet steel；
The torus is equipped with built-in iron core, iron core distribution annular in shape, and the magnet steel is samarium
Permanent magnet made of cobalt material molds press process.
Preferably, the prismatoid is isosceles trapezoid.
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 optimal service performance.
Foil temperature sensor: for sheet type, small volume is embedded in crozier, will not influence the usability of magnetic pole
Effectively sensing apparatus temperature change it can alarm in time, 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.
Therefore, the waist drum samarium-cobalt magnet provided by the utility model for motor, further lift structure assembly precision is high,
Properties of product are promoted, are prolonged the service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
