Arc magnet is not unfamiliar to many people, it is the same as other shapes of magnets, but also has many ways to magnetization method, then the arc magnet price and magnetization method has a relationship?
First, let's talk about the magnetizing method, there are three common ways to magnetize tile-shaped (arc) powerful magnets:
Method 1, tile-shaped powerful magnet alone magnetization, and then loaded into the housing, and then assembled as a whole;
Method 2, tile-shaped powerful magnets into the housing (sticking) and then magnetized, and then assembled as a whole;
Method 3: Tile-shaped powerful magnet is loaded into the case (glued), then assembled with finished products, and finally magnetized as a whole.
The accompanying picture shows a curved rare-earth neodymium magnet with galvanized surface.
The effect of different ways to magnetize the arc magnets:
1, Method one magnetization
The residual magnetism will be about 10% lower than the other two, some factories use solenoid tunnel type magnetization, the production efficiency will be relatively high;
3, Method two magnetization
It is possible to use internal or external charging, arc magnet needs to be glued and dried first, the production is also very convenient;
4, Method three magnetization
There are many small motors (mostly three slots) use this way, its rotor in the installation due to the lack of magnetism is very good assembly, but it is not convenient to check whether the magnet is filled.
Method 1 magnetization belongs to the open circuit magnetization, because there is no external magnetic field magnetic circuit, did not constitute a closed loop, generally lower than the closed-circuit magnetization will be; Method 2 is the most commonly used, belongs to closed-circuit magnetization, the magnetic flux density after magnetization is also the highest, and can be adjusted through the shape of the magnetizing head to adjust the waveform of the air gap magnetism to meet the requirements of different motor performance.
Is the price of a curved magnet related to the way the magnet is magnetized?
Generally speaking, the price of tile-shaped powerful magnets has nothing to do with the magnetizing method, but rather with the quantity ordered, the specifications of the curved magnets, and the grade level. The more you order, the more affordable; magnet specifications, the larger the price is more expensive. The higher the grade, the more expensive the specification.
