The design and performance requirements of smart drones have certain requirements for permanent magnet materials, mainly reflected in high performance, lightweight, durability and low energy consumption. The following are some common permanent magnet materials suitable for smart drones: 1. Neodymium Iron Boron (NdFeB) permanent magnet Features: Neodymium Iron Boron (NdFeB) is one of the strongest […]
Have many applications of permanent magnets in intelligent drones.They are widely used in intelligent drones, mainly in the following aspects: 1. Motor (brushless motor) Brushless motors are the core components of modern drone power systems, and the application of permanent magnets in motors is particularly important. Permanent magnet motors use the magnetic field of permanent […]
A magnetic levitation train, often abbreviated as maglev train, is a type of high-speed train that uses magnetic levitation technology to move. Here is a detailed introduction: Principle of Operation Levitation: Maglev trains rely on the principle of magnetic repulsion and attraction. There are electromagnets on the train and on the guideway. When the appropriate […]
Educational magnets: spray painting vs. stickers, which method is more suitable? When making educational magnets, it is crucial to choose the right surface treatment method. Spray painting and stickers are two common treatment methods, each with its own advantages and disadvantages. Let’s compare them in detail: Spray painting Advantages: Rich colors: Various colors can be […]
Why do most educational magnets use AlNiCo magnets? AlNiCo magnets are widely used in educational magnets, mainly due to their unique performance characteristics. Advantages of AlNiCo magnets Strong high temperature resistance: AlNiCo magnets have a high Curie temperature and can maintain stable magnetism even in high temperature environments, which is very important for some educational […]
Will permanent magnets rust when exposed to water? Permanent magnets rust? Yes! Although permanent magnets have strong magnetic properties, they are not “invulnerable”. Especially the common NdFeB magnets, whose main component is iron, are easily oxidized and rusted in a humid environment. Why do permanent magnets rust? Material composition: The main component of most permanent […]
The difference between FeCrCo and AlNiCo magnets FeCrCo (iron-chromium-cobalt) and AlNiCo (aluminum-nickel-cobalt) magnets are two distinct types of permanent magnets, each with unique properties and applications. Here are the main differences: Composition: FeCrCo magnets : Primarily made of iron, chromium, and cobalt, with possible additions of other elements like nickel or copper to enhance specific […]
What is Electropermanent magnet? An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by pulses of current in a winding of wire around the magnet portion. The magnet consists of two parts, one of a “hard” (high coercivity) magnetic material and […]
Main production process 1.Milling: The process begins by grinding the raw materials (aluminum, nickel, cobalt, etc.) into a fine powder. 2.Pressing: The powdered mixture is then pressed under high pressure in a mold shaped like the desired magnet. 3.Sintering: Next, the pressed material is heated in a hydrogen furnace at a very high temperature. This […]
