Abstract :

In this research, a new method is proposed to reduce the coincidence of the volume, losses and cost of making a DC motor without brushes using colonial competition optimization algorithms. In the first step, all electric motor relations are extracted and expressed based on its geometric parameters. In the second step, the function of competence, which is the same reduction in the volume, losses and cost of construction of a DC motor without brush, is defined on the basis of the relationships obtained in the previous stage. In the third step, the colonial competition algorithm is used to select the best values of the geometric parameters of the engine so that the objective function is minimized. The results of simulations show that the colonial competition algorithm has a good performance and can dramatically reduce the size, loss, and cost by appropriate selection of geometric parameters.
