  • Exchange Spring Magnet

Exchange Spring Magnet

Exchange Spring Magnet An exchange spring magnet is a magnetic material with high coercivity and high saturation properties derived from the exchange interaction between a hard magnetic material and a soft magnetic material, respectively. Coehoorn et al. were the first able to observe an actual exchange spring magnet.[1] Exchange spring magnets are cheaper than many [...]

  • 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 [...]

  • Magnetic Materials in Voice Coil Motors (VCM)

Magnetic Materials in Voice Coil Motors (VCM)

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 [...]

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 [...]

  • How Are Samarium Cobalt Magnets Made

How Are Samarium Cobalt Magnets Made

How Are Samarium Cobalt Magnets Made SmCo magnets are rare earth magnets with high magnetic energy product and extremely low-temperature coefficient. Its maximum operating temperature can reach 350°C. When working at a temperature above 180℃, its maximum magnetic energy product (BHmax), coercivity, temperature stability, and chemical stability all exceed those of the NdFeB magnet. But [...]

  • Select Material Grades for Neodymium Magnets

Select Material Grades for Neodymium Magnets

Select Material Grades for Neodymium Magnets When you are trying to figure out which neodymium magnets to select for your design needs, you would always see the term “grade” or “N rating” from any supplier or manufacturer. Besides a few other criteria, desired material grade must be defined for a neodymium magnet. So, what does [...]

  • Select Magnet Materials from MPCO Magnets

Select Magnet Materials from MPCO Magnets

Select Magnet Materials from MPCO Magnets ( Neodymium, NdFeB Magnets, SmCo, Alnico, Ceramic Magnets and others ) When choosing a magnet material to be incorporated into your specific application, their properties need to be identified and compared to correctly evaluate their functional workability and economic feasibility. Design engineers should consider the magnetic requirement, physical requirement, [...]

  • Reconfigurable 3D-printable Magnets

Reconfigurable 3D-printable Magnets

Reconfigurable 3D-printable Magnets with improved maximum energy product In conventional magnets, neodymium with added heavy rare-earths is used in order to induce high output and size reduction. But as deposits of heavy rare-earths such as dysprosium (Dy) and terbium (Tb) are disproportionately distributed, it is important to reduce the amount used due to supply issues [...]

  • Strong Magnet Magnetization Orientation

Strong Magnet Magnetization Orientation

Strong Magnet Magnetization Orientation How do you differ from the north pole of a strong magnet without being marked? Obviously, it is impossible to distinguish between eyes alone. The compass can be used to approximate the powerful magnet, and the pointer to the north pole of the earth points to the south pole of the [...]
