The difference between the motor magnetic ring and the magnet

When hearing the motor magnetic ring, many people think it is a ring-shaped electronic component, so it is called a magnetic ring, but it is not the case. There are many types of motor magnetic rings, so they are called magnetic rings or ferrite magnetic rings etc.

The shape of the motor magnetic ring itself is similar, and it is easy to make mistakes. The best way to recognize it is to see if it is magnetic. Generally, the magnetic ones are hard magnets. The so-called hard magnets are also called permanent magnets or magnets. The magnet is divided into positive and negative poles, and the main component of the magnet is ferric oxide. Magnets are generally used in horns, buttons, and generators. Everyone knows that the magnetic ring is different from its material. It is made of ferrite material, which is generally used for anti-interference. Its composition contains iron oxide, nickel oxide and zinc oxide. Many people also add magnesium oxide or recycled materials in order to reduce costs. The so-called recycled materials are damaged during production and transportation, and have gaps. After recycling, they are mixed with raw materials and produced. The performance of this magnetic ring is not very good. Yes, because it has gone through the first sintering, and the second sintering will burn out the resistance of the magnetic ring.

Sintering is also a difficult step in the production of magnetic rings. It is necessary to control the temperature of the furnace. The magnetic rings burned at low temperature are like uncooked rice, and the resistance of the magnetic rings will be burned if the temperature is too high. No, so this step is the most important. The magnetic ring is generally used for injection molding on various lines, and some are directly buckled on the equipment line. In short, it is inseparable from the place where there is interference. The magnetic ring is not magnetic like a magnet, and there are positive and negative poles, the positive pole absorbs, and the negative pole is opposite. The magnetic ring has no positive and negative poles, and no positive and negative poles means no magnetism. The magnetic ring is generally used in electronic equipment as an impedance effect to prevent the intrusion of external cluttered signals. It can make electronic equipment operate normally and achieve a peak effect.

Motor magnetic rings and magnets are very different. The above introduction to them is only a small part. They have been widely used in many industries. For more knowledge about motor magnetic rings and magnets, please pay attention to our company's industry knowledge .
