Linear Motor Magnetic Assembly Guide A Linear Motor Magnetic Assembly is an important magnetic component in a permanent magnet linear motor. It usually consists of multiple NdFeB magnets arranged according to a specific magnetic pole arrangement, pole pitch, and magnetization direction. The magnets are assembled with a steel back iron, yoke, or other support structures [...]
Ring magnets are versatile and can be used in a variety of applications, including scientific experiments, medical equipment, and manufacturing. They are shaped like a ring with a hole in the center and have north and south poles that can be segmented in different ways around the ring. The unique polarization of ring magnets allows [...]
What is Eddy Current Losses in Permanent Magnet Materials? Understanding and Minimizing Eddy Current Losses in SmCo and NdFeB Magnets Eddy current losses are a significant concern in rotating machinery, especially when using metal-based permanent magnets like Samarium-Cobalt (SmCo) and Neodymium-Iron-Boron (NdFeB). Core losses, which include both eddy current losses and hysteresis losses, must be [...]
Can NdFeB Absorb Objects 600 Times Its Own Weight? Not Exactly Magnets can pick up heavy objects. It is said on the Internet that NdFeB magnets can pick up objects 600 times their own weight. Is this accurate? Is there a formula for calculating magnet attraction? Today, I will tell you about the "attractive force" [...]
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 [...]
Motor Arc Segment Magnet Drawing Reference In the case where there is no or inconvenient to provide arc magnet samples, drawings are also very important for magnet manufacturers, which is related to the accuracy of arc segmented magnets, so custom or need motor arc magnet magnetic tiles (Ferrite arc magnet NdFeB arc magnet) When taking [...]
Neodymium Radial Magnetized Ring Magnets Application Schematic Regarding the radial magnetization of magnets, many people do not know much about the contact with them, so they do not have a strong concept of radial magnetization. Radial magnetic ring magnetization is actually diametrical magnetization, and their strong magnetic surface is on the side of the ring. [...]
