Orientation technology of anisotropic injection magnet

What’s the difference between the isotropic magnet and anisotropic magnet?

Isotropic magnet’s crystal grains do not have their easy magnetization direction lined up in a specific direction and whose magnetic characteristic is isotropic. On the other hand, a magnet whose crystal grain directions are aligned and have their easy magnetization direction lined up is called an anisotropic magnet. Isotropic magnet includes bonded magnet using melt-spun powders as the raw material and isotropic ferrite magnets, but their magnetic properties are inferior to those of anisotropic magnets. The isotropic magnet can be magnetized form any direction.

What’s the different between the isotropic magnet and anisotropic magnet during manufacturing process?
Unlike isotropic magnet, the anisotropic magnet must apply alignment field during its manufacturing process, then most of the magnetic domains will aligned in the same direction to deliver maximum magnetic output. This alignment field process called orientation technology.

What are the two ways of orientation technology for anisotropic injection magnet?
The orientation technology for anisotropic injection magnet includes permanent magnet orientation and electromagnetic orientation.

The sketches of electromagnetic orientation technology
According to magnet’s shape and final magnetization direction, the aligning direction of electromagnetic orientation technology includes axial-orientation and radial-orientation. Japanese injection magnet manufacturers have several years of experience in this area.

The sketches of permanent magnet orientation technology
The technical difficulty of the permanent magnet orientation is less than the electromagnetic orientation technology. The sintered NdFeB or SmCo magnets are embedded in the mold to generate magnetic field. The strength of magnetic field is affected by many factors. Engineers design it based on the experience and Finite element method.
