Radiation Ring Magnet Sintered NdFeB magnetic ring is a new product developed in recent years. It is mainly used in high-performance permanent magnet motors and sensors. In the application of permanent magnet motors, sintered NdFeB magnetic tiles are usually bonded into a ring, which has natural disadvantages: Since the processing of the tile-shaped magnet belongs [...]
Eddy Current Loss of Rare Earth Permanent Magnet Both samarium cobalt and neodymium iron boron are metal materials. Due to the good electrical conductivity of metal materials, the resistivity is very low. This is not a good thing for rotating machinery such as motors, because it will bring eddy currents to rotating machinery Loss, causing [...]
Magnetic Materials in Voice Coil Motors (VCM) Voice coil motor, VCM is a special form of direct drive motor, which can directly convert electrical energy into linear motion mechanical energy. The principle is to put a cylindrical winding in a uniform air gap magnetic field, and the winding generates a magnetic field. , Drive the [...]
Magnetic Materials in Loudspeakers (Horns) The core component responsible for producing sound in audio equipment is the loudspeaker, commonly known as the horn, whether it is a stereo or a headset, this key component is indispensable. The loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of the loudspeaker has [...]
Sintered NdFeB Weight Loss Test (HAST, PCT) Sintered NdFeB permanent magnets are the magnetic materials with the highest magnetic properties discovered so far, and are widely used in wind power generation, new energy vehicles, maglev trains, intelligent robots and other fields. Sintered NdFeB magnet adopts powder metallurgy process, and the raw materials contain highly active [...]
Magnetic Materials in Linear Motors Linear motor is a kind of transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion. It can be regarded as a rotating motor that is radially dissected into a plane (that is, a rotating motor is flattened, and works the same). Linear motors [...]
FeCrCo - Iron Chromium Cobalt Permanent Magnet Material The iron-chromium-cobalt permanent magnet material appeared in the early 1970s. It belongs to the age-hardening deformable permanent magnet material. Its alloy composition range is very wide. The basic composition is 20-33% Cr, 3-25% Co, and the rest is Fe. The magnetic performance of FeCrCo is equivalent to [...]
Soft Ferrites Applications Ferrites are polycrystalline oxides manufactured by ceramic technology and belong to a class of materials that exhibit the technically useful property of ferromagnetism. In a ferromagnetic material, magnetism occurs under the influence of an externally applied field. On removals of this field, material returns to its non-magnetic state. This behaviour is termed [...]
About LLC Converter Topology Power conversion is the process of converting electrical energy from one form to the other. The devices responsible for this conversion can work to convert alternating current (AC) into direct current (DC) & vice versa. They range from simple setups like a transformer to more complex conversion systems like resonant converters. [...]
Why are Ferrite Cores Used for Antenna Coils? Antennas have been used for many years to catch waves that are invisible to the naked eye. These electromagnetic waves travel around us, carrying information that’s grabbed by the antennas & used by the application it's attached to. Since all current-carrying wires around us develop their own [...]
Know About Ferrite Cable Cores As long as electronic items surround us, electromagnetic waves will be around us too. These waves are naked to the human eye and won’t affect your day-to-day activities. Born from the flow of electric current, these, however, can affect parts of devices like the power supply cable. The cable acts [...]
Know About Ferrite Core Transformers A transformer is a device used in the distribution and transmission of alternating current (AC). It does so by stepping up (increasing) or stepping down (decreasing) the voltage to attain the desired values. Hence, in simple terms, you can understand it as a voltage control device that works on the [...]
