Zj. Liu et al., A COMBINED NUMERICAL AND ANALYTICAL APPROACH FOR MAGNETIC-FIELD ANALYSIS OF PERMANENT-MAGNET MACHINES, IEEE transactions on magnetics, 31(3), 1995, pp. 1372-1375
This paper discusses finite element analysis of permanent magnet machi
nes using an annular macro-element for the air gap and magnet region.
It is shown that in comparison with the conventional finite element sc
heme, the proposed method provides stable computational prediction of
magnetic field problem, and can be used as design and analysis tool fo
r permanent magnet machines.
