摘要

Methods for analysis of three-dimensional magnetostatic problems in systems including permanent magnets are presented. Two ways of magnetostatic field description, using vector potential and scalar potential, are described. Numerical computations are performed using finite difference method. Non-linear characteristics of materials and permanent magnets are taken into account. Calculation results for a DC motor with permanent magnets are compared.
