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.
