Research on Leakage Permeance Calculation of Bar Permanent Magnet in Open Magnetic Circuit

Abstract:

For electric magnetic system which contains permanent magnet, its calculation results often has a low level accuracy when using equivalent circuit method .The calculation method of permanent magnet leakage permeance is the key point and needs to be improved. The leakage permeance calculation formulas of bar type permanent magnet are deduced. The magnetic field simulation method and analytical method for calculating leakage permeance of bar type permanent magnet in open magnetic circuit are investigated based on the finite element method. An example is given and the results are validated by experiment. The methods and results can be used to found the equivalent magnetic model with high accuracy.
