Abstract: Permanent magnet motors have been widely used. In recent years, from the point of view of energy saving, it is required to improve the efficiency of permanent magnet motors by applying an optimal design method. In this paper, we propose an adjusting technique of the supply voltage of permanent magnet motor when carrying out the optimal design by adopting voltage driven finite element method and genetic algorithm. In calculation for the optimal design, it is difficult to keep a desirable balance of the supply voltage and the induced electromotive force. By using the proposed method, the supply voltage is appropriately decided to generate the rated torque. Owing to adopting this adjusting technique, the computation time for the optimal design can be reduced and the solution can escape from local minima because the needless computations can be drastically reduced.
