The 775 dc motor is famous for its cost-effectiveness and wide applicability. Here are a few reasons why: Cost-Effective: 775 motors are relatively inexpensive but offer high performance and reliability for many low-cost and medium-power applications. Power and torque: the 775 motor can deliver higher power and torque than comparable models, which makes it widely used in applications requiring high torque, such as model making, DIY machinery, industrial automation, etc. Easy to control: 775 motors are easy to control, you can adjust the speed by adjusting the voltage, PWM control and other methods. Wide applicability: 775 motors are suitable for many different application scenarios such as robotics, DIY, model making, home appliances, etc., thus becoming one of the popular motor models. Good replaceability: due to its popularity and wide applicability, 775 motors have many manufacturers and brands in the market, so it is easy to find a suitable replacement motor. 12V 775 dc motor or 24V 775 dc motor, which is better for 775 motors?Choosing the voltage to use for a 775 motor should be based on the specific needs of the application. Speed and torque: The speed and torque of a 775 motor is related to the input voltage. Under the same load, a 24V voltage 775 motor will have higher speed and more torque, but it should be noted that at higher voltage it will also generate more heat and need better heat dissipation. Power: The input voltage also affects the power of the 775 motor. A 24V 775 motor will provide more power for the same load, but this also means that the motor will overheat more easily and require better heat dissipation. Controls: Using different voltages requires different motor drives, and some drives do not support higher voltages. Therefore, which voltage to use needs to be chosen based on the specifications of the chosen driver.  

The manufacturing process of rubber magnets is much the same as other products. In the design of the formula, the first to determine the species of magnetic powder, particle size and dosage. Next should be determined according to the requirements of the use of rubber, such as wear-resistant medicine selection of natural rubber. In the process, before or after vulcanization needs to be added to other products do not have the magnetization process, in order to give the product permanent magnetism. The advantage of magnetization before vulcanization is that the direction of the external magnetic field remains unchanged, through the rubber network is more smooth; after vulcanization magnetization through the poorer, but the operation is more convenient. In short, each has its own advantages and disadvantages. Rubber magnets, also known as bonded permanent ferrite magnet , are made of bonded ferrite powder, rubber or plastic and other materials, through extrusion, calendering or injection molding. Due to the high plasticity of the material itself, the finished or semi-finished products can be cut, perforated, longitudinally cut and mounted on other materials at will, and is not easy to demagnetize, has a good corrosion resistance, is mainly divided into two major categories of Isotropic Rubber Magnets and anisotropic rubber magnets. The difference is as follows: 1. Different magnetic properties: Isotropic rubber magnetism is weaker, while anisotropic rubber magnetism has a higher magnetic function. 2. Different working temperature and density, the density and temperature of the Isotropic rubber magnet are lower than that of the anisotropic rubber magnet. 3. Different application areas: the Isotropic rubber magnet is mainly used in refrigerator magnets, car stickers, printing products, and promotional items. And anisotropic rubber magnets, a large number of applications in micro-motors, computers, laser printers, copiers, magnetic toys and other areas of the preparation process of rubber magnets.

Rubber magnet is divided into homosexual and anisotropic, and the anisotropic magnetism is better. On this basis can be divided into single-sided magnetic and double-sided magnetic, and can choose to back rubber and not back rubber. Magnetic rubber sheet, also known as soft rubber magnet, is made of rubber with magnet powder and various cooperating agents after dense refining, calendering vulcanization and withdrawal vulcanization. Magnetic rubber sheet can be made into single-side magnetized and double-side magnetized, can be over UV bright (matte) oil; magnetic rubber sheet of the physical properties of the main characteristics of the high specific gravity, due to a large number of magnets added to the powder, the specific gravity of 3.8cm3 / g, is the heaviest specific gravity of the rubber sheet.

About ceramic magnet, many people do not know it belongs to which kind of magnet? Today, this article will introduce to you the material type, shape, application and its performance parameters of ceramic magnets. Ceramic magnets, also known as hard ferrite magnets, are composed of barium or strontium and were developed in the early 1960s as an alternative to more expensive metal magnets. These magnets are very hard, brittle, and have low energy properties compared to other magnetic materials. However, ceramic ferrite magnets are widely used due to their excellent demagnetization and corrosion resistance properties and superior price advantage. Ferrite magnets are manufactured by sintering or injection molding. These magnets can be anisotropic and isotropic. Anisotropic grades are oriented in the direction of manufacture and must be magnetized in that direction. Isotropic grades are not oriented and can be magnetized in any direction. Ceramic magnets can maintain 45% of their room temperature magnetic specification at 350 degrees Fahrenheit. The degradation is nearly linear as the temperature increases and the change in magnetization is essentially reversible until about 840°F, at which temperature the ceramic magnet is completely demagnetized. Ceramic magnets exposed to temperatures up to 1800 degrees Fahrenheit can be remagnetized for continued use. However, above 1800 degrees Fahrenheit, the changes are irreversible. Ceramic ferrite magnets are commonly used in shapes such as arc (tile), rectangle, square, torus, and cylinder. Applications for ceramic magnets include: loudspeakers, DC brushless motors, magnetic resonance imaging, magnetic separation for magnetic assemblies designed for lifting, holding and recycling.

The type of magnet material There are many types of magnet materials, common permanent magnets, ferrite magnets, neodymium magnets, Alnico magnets and so on. Different materials have different advantages and disadvantages, users should consider the use of the environment and needs when choosing magnets. Why there will be the case of broken magnets The reason why magnets are easy to crack, mainly because of the following reasons: 1. Quality issues: the manufacturing process of the magnet and the quality of the material directly determines whether the magnet is fragile. 2. Inappropriate use of the environment: such as high-temperature environment, humid environment, external forces, etc., will lead to fragile magnets. 3. Improper use: for example, forcing the magnet apart, using the wrong way to adsorb items, etc., will also lead to magnet damage or fragmentation. Which material of magnet is not fragile Generally speaking, magnets made of neodymium-iron-boron (NdFeB) are stronger and more durable than those made of other materials. NdFeB magnets are a kind of rare-earth magnets with very strong magnetic force and high wear resistance. Due to the continuous improvement of the production process and material quality of NdFeB magnets, nowadays NdFeB magnets are not easy to break. In addition, the magnetic force of NdFeB magnets is so strong that they can be used to make various kinds of iron absorbers, motors, computer hard disks and other high-tech devices.

In order to improve the corrosion resistance and aesthetics of magnets, the surface of magnets is often plated with a selection of different materials.Sintered NdFeB magnet coatings are nickel, copper, chrome, gold, zinc, black zinc, epoxy resin. Its surface plating is different, its color is different, its preservation time is different, each has its own advantages and disadvantages. 1, zinc: Zinc coating magnet surface is silver-white, can do 12-48 hours salt spray, can be used for some glue bonding.Zinc is widely used as a coating for exterior surfaces because of its good corrosion resistance and low cost. 2, Nickel: It looks like the color of stainless steel, and it is hard to be oxidized when put in the air. Besides, it has beautiful appearance and good luster. The Nickel coating magnet can pass the salt spray test of 12-72 hours. The disadvantage is that it can't be bonded with some glue, which will cause the coating to peel off. Accelerated oxidation, now the market does 120-200 hours of salt spray for nickel-copper-nickel plating method, but its plating cost is relatively high. 3、Copper: mostly appear in the hardware industry, sintered NdFeB strong magnet is rarely used, the appearance of yellow. 4, chromium: chromium plating industry is also relatively rare, its plating cost is very high, the general company can not accept. However, it has a strong ability to release decay and is difficult to react with other substances. It is mainly used in places with strong ph. The price of domestic products is relatively low, so there are few choices. 5、Black zinc: According to the customer's requirements, the surface of the product is treated with black color. For the electroplating process, on the basis of galvanization, a black protective film is added through chemical treatment. This film can also protect the product, increase the salt spray time and prolong the oxidation time. However, its surface is easily scratched and loses its protective effect. Nowadays, few people use it, most of them use resin to replace it. 6, epoxy coating magnet: NI, ZN, epoxy resin and the role of PARYLENE - C coating on the magnetic properties of NdFeB magnets in the three kinds of solution was studied. Polymer material > epoxy resin > nickel coating > zinc coating is a layer of resin paint on the outside after the product is nickel plated. Different magnet surface coatings have different characteristics and should therefore be selected according to the actual situation. For example, for surfaces that require high brightness, nickel and silver plating can be selected; while for occasions that require corrosion protection, zinc or nickel plating should be selected.

I. Internal structure of hollow cup motor Hollow cup motor is a new type of electric motor with a complex structure, including rotor, stator, drive circuit and many other components, of which the most important is the hollow cup rotor. The hollow cup rotor is a hollow cylindrical structure, which consists of several isolated motor coils inside, while the shell is made of highly conductive material. At the same time, there are also motor coils inside the stator, and the hollow cup rotor is continuously rotated by changing the direction of the electromagnetic field through the AC power supply. 2.The electromagnetic principle of hollow cup motor The working principle of hollow cup motor is based on the law of electromagnetic induction. When the current passes through the motor coil, a magnetic field will be generated around it, and the strength of the magnetic field generated between neighboring coils is different. In this case, the neighboring coils will interact with each other, and this interaction will cause the hollow cup rotor to rotate. Specifically, when current flows through a coil, a certain magnetic field is generated inside the coil. And since the hollow cup rotor also has a number of motor coils inside, the magnetic fields generated between these coils will interact with each other, thus creating a gravitational force and a repulsive force. By constantly changing the direction of the current, the direction of these gravitational and repulsive forces can be constantly changed, thus allowing the hollow cup motor to constantly rotate. 3. The application fields and future development direction of hollow cup motor Hollow cup motor is a very flexible motor, also called coreless dc motor,suitable for energy, aviation, robotics, medical equipment and other fields, widely used in transmission and control of high precision requirements of the occasion. In the future, with the popularization of various electronic devices and the development of robotics, hollow cup motors will have a wider range of applications. At the same time, the improvement of performance indicators and cost-effectiveness will also be the key to the future development of hollow cup motor.

Due to their excellent performance, Pot Magnets have a wide range of applications in industry and our daily life. What are the types of pot magnets, they are also mounting magnets with countersunk holes, countersunk holes, threaded holes, eyelets, hooks, internal threads, threaded studs/rods, or sockets for easy installation.The following are square pot magnets.Rectangular neodymium pot magnets. Advantages of Pot Magnets Pot magnets offer more advantages than individual NdFeB countersunk magnets: 1. Smaller size and stronger magnetic force: the steel casing concentrates the magnetic force on one side and greatly increases the holding power. 2. Cost saving: Due to the super strong magnetic force, the use of rare earth magnets can be reduced, lowering the cost of magnets. 3. Durability: Neodymium magnets are very brittle and steel or rubber coverings protect them. 4. Mounting options: pot magnets can be applied to many accessories, so they can be used with different mounting options If you need magnets that only need one side to suck things and the other side to hold them in place, then you can choose pot magnets, as strong individual magnets are costly. Without considering the external factors, single strong magnet and pot magnet with the same pulling force, the pot magnet is preferred, the biggest reason is that the iron shell inside will concentrate the magnetism on one side, which maximizes the pulling force of the whole set of pot magnets, and the price is much cheaper than the single strong magnet.
