Abstract
The utility model relates to a magnetic steel and particularly relates to a high-precision neodymium iron boron magnetic steel for a motor. The high-precision neodymium iron boron magnetic steel comprises a magnetic steel body, wherein the magnetic steel body is a cylindrical structure, the magnetic steel body is provided with a displacement transmitting sensor, an upper portion and a bottom portion of the magnetic steel body are respectively provided with uniformly-distributed friction bars, the material of the magnetic steel body is neodymium iron boron magnetic steel, and a surface of the magnetic steel body is provided with a color-zinc layer. The high-precision neodymium iron boron magnetic steel for the motor has a compact structure, improves product performance and prolongs service life.
Description
Technical field
The utility model is a kind of magnet steel, particularly a kind of high accuracy Nd-Fe-B magnet steel for motor.
Background technology
Magnet steel of the prior art, complex structure, and also fixed form is insecure, and result of use is not good, causes reduce its useful life.
Chinese patent 201020150678.5, discloses a kind of magnet, particularly a kind of samarium cobalt magnet with cambered surface that is mainly used in microwave communication technology, audio-visual technology, electrical engineering etc.Comprise magnet, described magnet pack is drawn together contour body and square body, and described contour body and square body are integrated, in described magnet, are provided with intermediate layer, and intermediate layer is coated with nickel coating.This structure relative complex, useful life is relatively low.
Summary of the invention
The utility model is mainly to solve the deficiencies in the prior art, compact conformation, and lifting assembly precision greatly promotes the high accuracy Nd-Fe-B magnet steel for motor of serviceability simultaneously.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of high accuracy Nd-Fe-B magnet steel for motor, comprise magnet steel, described magnet steel is cylindric, in described magnet steel, be provided with displacement emission sensor, the top of described magnet steel and bottom are respectively equipped with equally distributed fricting strip, the material of described magnet steel is Nd-Fe-B magnet steel, and the surface of described magnet steel is provided with color zinc layer.
Displacement emission sensor: when the displacement occurring in motor when magnet steel exceedes, displacement emission sensor is sent signal to control centre.
As preferably, the diameter of described magnet steel is 8.42～8.58mm, and the length of described magnet steel is 29.95～30.05mm.
As preferably, the outer knuckle of described magnet steel is respectively arc chord angle.
Therefore, the high accuracy Nd-Fe-B magnet steel for motor that the utility model provides, compact conformation, improving product performance, increases the service life.
