When you hear the magnetic ring of a motor, many people think it is a toroidal electronic component, so it is called a magnetic ring, but it is not like this. There are many kinds of magnetic rings in motors, so they are called magnetic rings or ferrite magnets. Ring etc., so it is called many names, let's take a look at it.

The shape of the magnetic ring of the motor itself is similar, which is prone to errors. The best way to identify them is to see if there is any magnetism. Generally, magnetic is hard magnetic. The so-called hard magnet is also called permanent magnet or magnet. The magnet is divided into a positive electrode and a negative electrode. The main component of the magnet is iron tetroxide. Magnets are usually used for horns, buttons and generators. Everyone knows magnetic rings. Unlike the material, it is made of ferrite material. It is usually used for anti-interference. Its composition contains iron oxide, nickel oxide and zinc oxide. Many people add magnesium oxide or recycled materials to reduce costs. The so-called recycled materials are damaged during production and transportation. animal. After recycling, the raw materials in the production distribution. The performance of this magnetic ring is not good. Because it has experienced the first sintering, the second sintering will burn out the resistance of the magnetic ring.

Sintering is also a difficulty in the production of magnetic rings. The temperature of the furnace must be controlled. A magnetic ring that burns out at low temperatures is like uncooked and cooked rice. If the temperature is too high, the resistance of the magnetic ring will be burned. No, so this step is the most important. Magnetic rings are usually used for injection molding of various circuits, and some are directly connected to equipment lines. Generally speaking, there is interference in indivisible places. Magnetic ring magnets do not have a positive pole and a negative pole like a magnet. The positive pole is absorbed while the negative pole is opposite. The magnetic ring is not divided into positive and negative poles. Without positive and negative electrodes, it is equivalent to no magnetism. The magnetic ring is usually used as an impedance function on electronic equipment to prevent the intrusion of external clutter signals, which allows the electronic equipment to operate normally and has a peak effect.

Motor magnetic rings and magnets are very different. The above description is only a small part and has been widely used in many industries.
