Abstract:
This paper develops a parametric finite element analysis
package for the electromagnetic fields in electrical
machines. Based on Petri net, a parametric finite
element geometrical modelling method is presented, with
which the user can interactively utilize variables to
describe the dimensional and geometrical constraints.
The efficiency of revision of finite element geometrical
model is enhanced. An electromagnetic finite element
adaptive mesh generation method based on fuzzy logic
control is proposed, by which more appropriate mesh
distribution can be obtained A V-A model of switches is
developed, which has been applied to the dynamic
simulation of magnetic field coupled with drive circuits.
Comparing the simulation results with the experimental
observation, the satisfaction of this model is confirmed.
The advantages of this package are its precision and
flexibility. These will significantly make the user focus
more on their individual physical problems.
