Optimization of induction motor design has been receiving considerable attention in recent years because of both the rising cost of raw materials and energy. Minimization of active material cost has been the primary focus of attention of the motor manufacturers and hence much research in this area has taken place. From the user's standpoint, the operating cost of the machine during its lifetime is of greater importance. Therefore, the design of an induction motor should also emphasize the minimization of its active loss cost. This objective would also contribute towards the global need for energy conservation. A new method of computer-aided design optimization of a three-phase induction motor is proposed. Due to the highly non-linear nature of the design optimization problem an approach using the modified Hooke--Jeeves method is employed. The optimization of the objective function (motor efficiency) is deduced in terms of eight independent motor design variables which are then used to predict seven performance indices and the cost index of the machine.
