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 [...]
