Design of modern electrical machinery to operate at high power densities and optimal efficiency requires accurate performance prediction. To accomplish this objective, magnetic field analysis must be performed taking full account of three-dimensional effects and iron saturation. In this paper, a three-dimensional magnetostatic analysis using a hybrid finite-element formulation is presented. The method employs a combined vector and scalar formulation for representing the magnetic field. The analysis developed in the paper is applied to a permanent-magnet synchronous machine for evaluating the field distribution on no-load, in the body of the machine and the end region. Since the operating regime of this particular machine is in the unsaturated region, it was sufficient to implement a finite permeability case. The method described could be easily extended for the full-load case and the nonlinear algorithm implemented.
