Introduction to the Application of Hall Sensing in Multipole Sintered Ferrite Magnets Huoran induction magnet is mainly used for precision motor speed control, and the characteristic of the magnet is mainly to use the induction of the N and S poles of the magnet, so the magnet is basically a magnetizing method of 2-26 poles. The outer diameter is generally between 4mm and 30mm, and the shaft hole may vary depending on the customer's usage.Our company's Hall induction multipole ferrite magnets mainly have outer diameter magnetization and flat surface magnetization methods, and there are also various materials, such as ceramic ferrite, rare earth neodymium iron boron, injection molding magnets, etc.The performance of a ferrite multipole magnetic ring cannot be measured by the surface magnetism of the product, nor can the performance of a product be tested by the surface magnetism of the ferrite multipole magnetic ring. This is because the ferrite multipole magnetic ring itself belongs to a product with magnetic pole differentiation, and the same product will detec: 18

Solution for customers not paying a deposit for customized magnets In response to the above situation and in order to prevent accidents, we must require customers to make a deposit in advance. If customers do not agree to make a deposit in advance, we must not hastily produce, especially ferrite magnets, because ferrite magnets are different from neodymium iron boron strong magnets. The production of ferrite magnets requires molds to achieve production, and a small production volume will be a very troublesome matter. Once customers cancel the order, So the products produced cannot be sold and can only be used for backlog or destroyed for re production.If the customer insists on not paying the deposit, our only solution is to cancel the order. In the absence of a deposit, the risk of hastily producing ferrite magnets is greater than the actual benefits obtained. The most rational scenario is to persuade the customer to pay the deposit, send samples for confirmation after the goods are ready, and arrange for delivery and receipt of the remaining payment: 18

Do you want to produce customized ferrite cutting magnets without paying a deposit What are the hidden dangers of customers not paying a deposit for customized magnets?1. The order has been cancelled midway through productionWithout any reason, I don't want it anymore and I won't be able to contact you again. You can produce it. After production, put it in the warehouse and wait for the Chinese New Year!2. Don't refuse after arrivalIt is said that people stand firm without faith, but in this society, there are always people who do not want to deliver goods, especially those from other places, which is even more troublesome. So all losses are borne by the company.3. Find cheaper suppliersI have a colleague who paid a 10% deposit of only a few hundred yuan in advance. In the end, I found a cheaper one and decided not to accept it. In the end, I had to sell it at a low price.: 18

Comparison of injection molding (rubber plastic) magnetic and bonded permanent magnet processes The magnetic force of injection molding is weaker than that of anisotropic ferrite and stronger than that of isotropic ferrite. The process and injection molding of injection molding are basically the same as that of bonded permanent magnets. The only difference is that this process involves squeezing the heated particles into a mold through a hole to form the product, which is also rigid. The adhesive used is the same as injection molding, with a dosage of about 20% (volume). This process is generally used to produce thin or thin-walled circular magnets that are difficult to achieve by other bonding processes. It evolved from the manufacturing of injection molded plastic products. Firstly, the magnetic powder and binder are mixed evenly, then mixed and granulated to produce dry pellets. Then, the pellets are sent to a heating chamber with a spiral guide rod for heating, injected into the mold for molding, and cooled to obtain the product. The magnetic particles used are generally ferr: 18

Where are ferrite multipole magnetic steels mainly used? Most multi-stage magnetic rings are used for brushless Hall induction components in brushless motor motors, but the production and processing process of permanent magnet ferrite magnets is much more complex than rare earth neodymium iron boron strong magnets. laymen believe that the production process of permanent magnet ferrite magnets is simpler than neodymium iron boron strong magnets. In fact, this is a wrong view because they do not understand the production process of permanent magnet ferrite magnets and rare earth neodymium iron boron strong magnets.The production and processing technology of neodymium iron boron magnets in the Pearl River Delta region is mostly a post processing manufacturer, which directly purchases raw materials from material suppliers and processes them into finished magnet products. From the perspective of processing and production technology, it can be divided into four main steps: purchasing raw materials, slicing, processing, producing, electroplating, a: 18

Schematic diagram of strong magnetic pulling force of neodymium iron boron Many customers have called or contacted our magnet manufacturer through QQ, but since they themselves do not know what specifications and performance of material magnets they need, they directly ask, 'What size of magnet is required to lift multiple and multiple items?'?The magnetic force requirements for magnets vary in different fields and product designs. What the editor wants to say is that the suction force of a magnet is not only related to the size of the magnet, but also to the direction in which the object is attracted,The thicker the iron plate, the greater the suction force, the larger the contact area, and the greater the suction force. The vertical direction is the maximum pulling force direction, and the horizontal direction is the minimum pulling force direction. Therefore, we often translate and push the magnets that are adsorbed together.: 05

The main differences between the vertical and horizontal pulling forces of magnets are as follows 1. Vertical tension refers to the attraction or attraction force of a magnet in the vertical direction, while horizontal tension refers to the attraction force of a magnet in the horizontal direction.2. In the absence of external forces, the maximum vertical pulling force of the magnet is greater than the maximum horizontal pulling force, because gravity enhances the vertical attraction.3. The vertical tensile force rapidly decays as the distance between the magnet and the object increases, but the attenuation of the horizontal tensile force is slower.4. The vertical pulling force is more dependent on the magnetic properties of the magnet itself, while the horizontal pulling force is also related to the magnetic circuit design in addition to the magnetic properties.5. Horizontal tension can continue to transmit motion through mechanism design, but vertical tension can only generate static attraction.6. In a motion system, vertical suction is often used first to obtain fastening, and th: 05

Distance between magnetic switch magnet and reed tube? It is similar to Hall elements, but its principle and properties are different. It is a switch element that uses magnetic field signals to control, without magnetic disconnection, and can be used to detect the state of circuits or mechanical movements. Another type of magnetic switch is the proximity switch, door magnetic switch, or sensing switch in the market. It has a mold and is a standard size plastic shell, Seal the reed tube in a black shell and lead the wire out. Fix the other half of the plastic shell with a magnet on the other end. When the magnet approaches the switch with the wire, it sends a switch signal, which is usually connected at a distance of 10mm.Another type of magnetic switch is to set one or more magnetic spring switches inside a closed metal or plastic tube, and then run the tube through one or more hollow floating balls with ring shaped magnets inside. The fixed ring is used to control the floating ball and magnetic spring switch in relevant positions, making: 05

What are the factors that affect the magnetic force of a circular magnet? Magnets are becoming more and more widely used in today's social life. Whether in life or work, we sometimes come into contact with magnets. The development of magnets is so good mainly because they have a wide range of applications. However, we should not only see one side of their halo, but also explore their different aspects. Magnets have some differences, So we should pay attention to these aspects of magnets.Let's start by saying that circular magnets cannot be used in some cases due to their different shapes. This is due to their own reasons, and we cannot change them. However, in some places, they have similarities with other magnets. So what factors are affecting their magnetic performance? The first factor is environmental factors. As circular magnets are mainly presented in a circular shape in front of us, there are certain differences for some special environments. In addition, there is a temperature factor. If the magnet encounters high temperatures, corrosion will: 28
