High Magnetic Flux Density Sintered Neodymium Magnet For Traction Motors Multi-Polar Magnetic Orientation

Introduction

Neodymium Iron Boron (NdFeB) or Neodymium magnets are extremely strong for their size. Shapes include rings, blocks, discs and custom.

To prevent unwanted oxidation, neodymium magnets are usually finished with a zinc, nickel or epoxy coating.

 

Manufacturing - In general, the elements are melted together and milled into a powder that is dry-pressed to shape in the presence of a magnetic field.

 

The material is then sintered, ground to dimension, magnetized and tested. They are called “rare earth” magnets because the elements of neodymium are classified as such in the lanthanides section of the Periodic Table of the Elements.
