PS-PERMAG - Software for Analysis of Permanent Magnets

PS-PERMAG in its current version 2.5 enables the user to do easy and fast analyses of the fields originated by permanent magnets. In general expensive FEM software is used for this purpose, which demands many efforts and lots of knowledge. Such programs generally can be handled by specialists only. In contrast  the software PS-PERMAG offers the computation of 3D field distributions by simple input of the magnets dimensions, its remanence induction and its pole number. PS-PERMAG supplies this for the most usual geometric versions of permanent magnets.

PS-PERMAG 2.5 shows the following characteristics:

easy definition of the problem by input of geometry, pole number and remanence

immediate 3D computation of all  field components, absolute field value and other parameters

analysis internal and external to the magnet

handling of eight different sorts of permanent magnets with adjustable pole configurations up to 256 poles

including soft magnetic materials and forces for specific sorts of magnets, now in addition with configurations for electrical machines

computation of field angles with axes of result coordinate systems

Fourier analysis of periodic and non periodic field distributions

circular and linear field paths for all sorts of magnet configurations, selectable result coordinates

graphical diagrams as well as listings in tabular form

ASCII export for using the results in external software

extensive help system

The following sorts of magnetic geometry are supported in the current version 2.5 of PS-PERMAG:

(n_p poles per pole area)

axially multipolar cylinders, also with soft magnetic plates of adjustable distance and computation of attracting force (n_p=1 to n_p=256 )

2D-Models for electrical machines, magnetization homogeneously multipolar and radially multipolar, inner and outer rotor assemblies (n_p=2 to n_p=256 )

Homogeneously multipolar cuboids, also with soft magnetic plates of adjustable distance and computation of attracting forces (n_p=1 to n_p=256 )

Example: Four pole magnet above soft magnetic plate

The following magnetic materials are treated:

All modern permanent magnetic materials, i.e.:

Ferrites, NdFeB, SmCo, SmFeN. It is not advisable to use PS-PERMAG for magnets made of Alnico or for magnetically semi hard materials. These materials show highly bent demagnetization curves, that do not fit to the model of rigid magnetization being used by PS-PERMAG .
