Influence of choice of permanent magnet electromagnetic parameters in the research of electrical devices

Abstract

The paper gives an insight to the importance of choosing one certain value in a range for the permanent magnets parameters given by manufacturers. The purpose of the research is to test the influence of chosen parameters values, which are given in a range and are used in computational modeling, on the devices main characteristics, as nowadays scientists and product developers are using more and more different simulation tools. Paper includes the electromagnetic field modeling, based on the finite element analysis and the electromagnetic measurements, obtaining the hysteresis loops of permanent magnets.
