5 Tips Introduction of NdFeB Magnet Production Process

5 Tips Introduction of NdFeB Magnet Production Process 1. Forming orientation: Process introduction: The function of orientation is to turn the easy magnetization direction c-axis of chaotically oriented powder particles to the same direction to obtain the maximum remanence. The main purpose of compaction is to crush the powder into a certain shape and size, [...]

How are Sintered Samarium Cobalt Magnets Made?

How are Sintered Samarium Cobalt Magnets Made? Developed in the early 1960’s, samarium Cobalt magnets have been a highly preferred application choice as a type of rare earth permanent magnet material. Samarium cobalt magnet compositions are primarily samarium and cobalt with small amounts of iron, copper, zirconium depending on the material grade. The powerful sintered [...]

Rotor magnet shaping technologies for permanent magnet electrical machines

Rotor magnet shaping technologies for permanent magnet electrical machines Engine torque ripple is essential for the comfort of vehicle passengers. Large torque ripple may result in a harsh driving experience. Moreover, additional noise and vibration are byproducts of torque ripple. The service life of the machine and attached components can be influenced by severe vibrations. [...]

Permanent Magnet Appearance

Permanent Magnet Appearance 1, Can customers specify appearance requirements? Yes. MPCO MAG was founded upon the ideology of custom solutions. We encourage customers to specify mechanical and/or appearance requirements. Of course, if no customer-specific standards are stated, MPCO adheres to its own Permanent Magnets Workmanship and Appearance Standard. 2, Does MPCO Magnetic Technologies have standards [...]

  • Rare Earth Magnet Manufacturing Process

Rare Earth Magnet Manufacturing Process

Rare Earth Magnet Manufacturing Process There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via “liquid phase sintering”. Therefore, these magnets are most often called sintered magnets. Ferrite, Samarium Cobalt (SmCo) [...]
