Abstract

Knowing the magnetic properties of electrical steel

is very important to build highly efficient electrical machines.

Many approaches, which are either of mathematical, physical or

phenomenological kind, were developed in the past in order to

predict the phenomenon of hysteresis in case of unmeasured

conditions. In this paper, a phenomenological 3D hysteresis

model using magnetic dipoles, which are mechanically supported

on a 3-dimensional grid, is presented. The different interactions

between these dipoles are based on the equations of

micromagnetism. Instead of minimizing the free energy in the

system by mathematical optimization methods, each elementary

dipole is able to rotate into an individual energetically favourable

positon due to its mechanical mounting. In the following sections

the model, its parameters and the identification process are

presented. Afterwards, the results of the parameter identification

process for a measured hysteresis are shown. Furthermore the

predictive abilities of the model in case of unmeasured conditions

are discussed.
