Developments in permanent magnet materials such as alnicos, rare-earth cobalts and ferrites have brought in their wake new interest in their application to the design of electrical machinery, torque couplers, lifting magnets, and other electromechanical devices. In all these cases, the magnetic field provides the medium for energy conversion. The accurate computation of the magnetic field distribution is essential for realistic performance prediction at the design stage. Progress in digital computers has made it possible to apply numerical methods such as the finite element technique for stable, reliable, and accurate computation of the electromagnetic field. This paper describes the application of the three-dimensional finite element analysis method for modeling permanent magnet axial-field machines, taking into account the complex disposition of the magnets, conductors, iron parts, material characteristics and boundaries.
