Abstract

A six pole 3 kW synchronous motor with rare earth magnet excitation is used as an ex‐ample for mathematical design optimization on the basis of the FD field calculation method. The nonlinear field of the machine at full load, excited by both the rotor magnets and the stator current, is determined. The resulting vector‐optimization problem is transformed into a scalar problem, i.e. only one objective is minimized, while the others are considered by nonlinear constraints. Either the magnet mass or the machine volume is minimized for a restricted power input. The results of the investigations are presented by the material contours, flux plots and by the electrical and mechanical data of the optimized machines.
