2D – Analytical method for proofing the magnet design for their magnetization in comparison with Finite Element Analysis

Permanent magnet applications were greatly inhibit  the technologies today where each and every rotation machine does goes with atleast one permanent magnet. With the innovation in technology, the need for innovate in the field of permanent magnet becomes necessary. The evolution of material for permanent magnet has catered a greater impact in the field of permanent magnet applications. Permanent magnet application becoming versatile in today technologies, it’s a concern to have the design and design study of permanent magnets.

In this regards, high energy magnetic materials for permanent magnet plays a vital role in the field of designing a permanent magnet applications. NdFeB permanent magnet are taken into consideration for computing the flux density along x-axis and y-axis, Bx  and By respectively. The behavior of sintered and bonded NdFeB magnet were computed theoretically and it has been analyzed using FEA package for comparison and confirmation

For instance Sintered NdFeB magnet and Bonded NdFeB magnet were considered with different proportion of loading of material say for compression molding 80% material loading required and for injection molding 60% material loading required along with a binding agent. Here material for permanent magnet has been choosen with Br = 0.9T, Hc = 540kA/m, BHmax=130kJ/m3

The flux density of the bar magnet is computed with magnet having the specific dimension for Bx(x,y)and By(x,y) and  has been compared with results from using FEA of 2D FEA Package.
