Speed sensor magnet The Hall speed sensor magnet is mainly used in locomotive control systems to provide necessary guarantees for vehicle driving safety. Its working principle is that when the sensor's rotating mechanism rotates under external driving, it will drive the permanent magnet to rotate. The magnetic field passing through the Hall element will undergo periodic changes, causing changes in the output voltage of the Hall element. Through subsequent circuit processing, a stable pulse voltage signal is formed, As the output signal of the vehicle speed sensor.Usually, automotive speed sensors use injection molded magnets, such as injection molded neodymium iron boron multipole rings, injection molded ferrite multipole magnetic rings, and sintered ferrite radial multipoles, usually 4 or 8 pairs of poles (8 poles and 16 poles). We produce all these materials of magnets.1. D25.5 * 6.1 * 5.3/radial external charging 4-pole, around 550 Gauss2. Injection molded ferrite D24 * 16 * 5.65/diameter outer 8-p: 18

Several common magnetization methods for multipole magnetic rings A multipole magnetic ring is a type of magnet commonly used in motors, sensors, robots, and automation equipment. Unlike ordinary magnetization, there are multiple magnetic poles on one surface. In addition to differences in material, they also have differences in magnetization methods. Generally speaking, the material determines the magnetic field strength (magnetic properties) of the multipole magnetic ring, and the magnetization method determines its application.1. Axial multipole magnetization2. Radial multipole magnetization3. Outer diameter multipole magnetization (radial external charging)4. Inner diameter multipole magnetization (radial inner charging)5. Planar multipole magnetization6. Single sided multipole magnetization7. Full radial magnetization (radiation magnetization)8. Slope multipole magnetization: 18

The processing of tile shaped magnet (iron) grinding machines can be divided into these three types In the process of producing magnetic tiles (tile shaped magnets), grinding machines are often used for processing. Today, high-strength magnet manufacturers will tell you about the three types of tile shaped magnet (iron) grinding machines for processing.1、 Simple grinding machineSeparate grinding processes are used to grind one of the bottom, side, inner arc, and outer arc surfaces. Due to low grinding speed and unreliable clamping positioning, the machining accuracy is not high, and only rough machining can be performed to solve the consistency of the blank.2、 Single station grinding machineSeparate processes are used to process one of the surfaces, including the bottom, side, inner arc, and outer arc. The difference between this type of grinder and a simple grinder is that the machine tool has a reasonable structure, high accuracy, and high grinding speed, resulting in high precision and good consistency of the product.3、 Through type grinding machineFor manufacturers producing larg: 18

Analysis of the reasons for insufficient magnetic force of rare earth neodymium iron boron magnets When using neodymium iron boron magnets, there may occasionally be customer feedback that the magnetic force of the magnet is insufficient and cannot meet the product's usage requirements, which affects the use of the product. What exactly is going on? Without further ado, let's move on to the topic below.The performance grade, coercivity, residual magnetism, intrinsic coercivity, maximum magnetic energy product, working temperature, and other important parameter data of neodymium iron boron magnets are also parameters that customers need to refer to for customized procurement. Insufficient magnetic force is caused by multiple reasons.From the customer's perspective, customizing neodymium iron boron magnets also requires their own customer's requirements for product parameters. At the same time, these parameters are provided to the magnet manufacturer, and the manufacturer can customize production according to your requirements. If the parameters provided by the custome: 18

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
