Abstract :
This paper discusses finite element analysis of permanent magnet machines using an annular macro-element for the air gap and magnet region. It is shown that in comparison with the conventional finite element scheme, the proposed method provides stable computational prediction of magnetic field problem, and can be used as design and analysis tool for permanent magnet machines
