Abstract

The basic equations of two scalar potentials and their finite-element discretized formulations are discussed. In order to compute the 3-D magnetic field in a complex solution domain, a method of hybrid elements consisting of tetrahedron, triangular prism, and arbitrary hexahedron is used, and its feasibility is justified by theoretical analysis and numerical examples. This method is successfully used to calculate the 3-D nonlinear magnetic field in a claw-pole electric machine with a power rating of 500 W
