Furniture magnet market share

Furniture magnet, widely use in kichen cabinet door(or drawers) for holding. It is made by plastic shell (or) steel shell and ferrite magnet inside(or neodymium magnet). Plastic shell+ferrite magnet inside, its price will be cheaper, of course iron shell+neodymium magnt, its price will be higher. ...

What the difference between flated ring magnet and rounded ring magnet?

Flated ring means ring magnet’s surface is flat, whatever front side or back side all of them are flat. Flated ring magnet is rarely to be used in the market. But some of customers has its request because it will be easily for their assembly. Rounded ring means ring magnet’s surface is rounded, it l ...

How many types for motor magnets?

Here motor we said is DC motor, because AC motor do not use magnets. There are 4 types of magnets to use at the application of motor: Ndfeb magnet in arc shape Magnetic is strong, the size of the motor can be smaller while maintaining the same power, and the starting current ...

Is it a must to use magnets for servo motors?

Servo motor is divided into AC Synchronous and AC Asynchronous. If it is AC synchronous motor it has to use magnet parts, the main material is Ndfeb; if it is AC asynchronous motor, that is not necessarily to use magnetic materials. What kind of magnet of the rotor inside the servo motor? The answer ...

Is there a non-friable magnet?

First of all, most of the magnets are easy fragile, not the problem of the quality of magnets. Here we said “most” is because there is still a small part of magnets that are not easy fragile. chip-off and cracks on ferrite magnets In fact, the magnet is fragile will be depend on i ...

HOW IS FERRITE MADE

Mixes of metal oxide powders and various binding agents are placed into a mold, heated, and squeezed until the ceramic is created. This process is called sintering. If the ferrite is to be made into a magnet, the hot ferrite may be magnetized so that when it cools, the magnetism is retained. Ferrite ...
