| Abstract |
This paper gives an overview on different modelling methods of axial flux surface mounted permanent
magnet machines. Due to the inherent 3D geometry of axial flux machines, the reduction of the design
problem to a 2D plane on the average radius of the machine does not yield to accurate computation
results in cases in which the magnet shape is complex. Particularly, the obtained curvatures and peak
values of torque and back-EMF may be strongly erroneous. A practical accuracy can be achieved in
those computations also by using quasi-3D computation method with analytical or 2D finite element
models. The most accurate method to predict the performance of axial flux machine is a real 3D FEM
modelling, but as a drawback it is often too time consuming to perform. This limits its efficient use in
daily design work. In this paper an overview to the different design methods and their applicability in
a design of axial flux surface mounted permanent magnet machines is presented. |
