Can NdFeB Absorb Objects 600 Times Its Own Weight? Not Exactly

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

Radiation Ring Magnet

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

Eddy Current Loss of Rare Earth Permanent Magnet

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 [...]

Sintered NdFeB Weight Loss Test (HAST, PCT)

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

Magnetic Materials in Linear Motors

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

Motor Arc Segment Magnet Drawing Reference

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

Neodymium Radial Magnetized Ring Magnets Application Schematic

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. [...]

  • How does Encoder Magnetic Ring See the Number of Poles

How does Encoder Magnetic Ring See the Number of Poles?

How does Encoder Magnetic Ring See the Number of Poles? The magnetic ring on the encoder is mostly made of ferrite, such as sintered ferrite, injection molded ferrite, and the number of magnetized poles is generally more. How to see the number of poles for the encoder magnetic ring? Some netizens have made difficulties. The [...]

  • Function and Use of the Magnetic Pole Sheet

Function and Use of the Magnetic Pole Sheet

Function and Use of the Magnetic Pole Sheet We can't see the magnetization method of magnet products with the naked eye. We don't know whether it is ordinary magnetization or multipole magnetization. We can only check it by using the magnetic pole observation piece, and judge the magnetization method and the number of magnetization poles [...]

  • How Much is a Sample Neodymium Arc Magnet

How Much is a Sample Neodymium Arc Magnet?

How Much is a Sample Neodymium Arc Magnet? Sample Neodymium Arc Magnet refers to testing before subsequent mass production, small-scale trial production, mainly for engineers to test and analyze whether the motor is running normally. Since the motor usually uses multi-piece tile-type magnets, for cost considerations, many purchasers will ask you how much does a [...]
