The optimization method is often used for designing the configuration of electromagnetic apparatuses, in order to enhance the performance. Many optimal design methods have been developed and popularized. However, most of the optimal design methods can take into account a single objective function. Therefore, when the problem has a few purposes, a weighted summed objective function is usually employed. Recently, we have proposed a new method taking into account the multiple purposes simultaneously and individually. The proposed method can select one rational solution from among the Pareto optima, based on the game theory. However, the meaning of the selected rational solution is unclear. Therefore, the meaning is investigated by calculating the weight parameters of the weighted summed objective function so that the optimal solution of the weighted summed objective function is identical to the rational solution of the game theory. We can intuit the meaning of the rational solution by comparing with the weight parameters.

“…In addition, it is required to reduce the product cost of PM motors. Many researchers have studied motor design methods [1], [2], [3], [4], and, over recent years, an optimal design method has attracted attention. It was reported that the shape of a PM motor, ased on such parameters as teeth width, teeth length, magnet size, etc., was optimally designed for the purpose of increasing the efficiency under a torque [1].…”

In this paper, we propose an economically-efficient optimal design method of different-size interior permanent magnet (IPM) motors to maximize their efficiency. Since the homothetic shape is used, the optimization design is, at once, performed. The use of the commonalized design can reduce the productive costs. Game theory is employed as an optimization method. The game theory can simultaneously increase the efficiency of all the interior permanent magnet motors with the common and homothetic shape. So far, there are no previous reports considering both the "economical efficiency" and the motor performance simultaneously. Therefore, the proposed optimal design method of the commonalized different-size interior permanent magnet motors using the game theory method achieves a high electrical efficiency in addition to the economical efficiency due to design optimization.

Inductively coupling power transfer is an emerging technique, which enables power transfer to loads through air. The contactless transformer is the key component of it, and the design of a transformer is a time-consuming work with a large number of tests. In this paper, a design method of contactless transformer with finite element analysis is presented. First the contactless transformer model is deduced from Maxwell Equations, and the self inductance and mutual inductance computational equations are given as well. Then the magnetic field distributions of contactless transformer with different air gaps are presented by simulation of MAXWELL ANSOFT. Furthermore, the skin and proximity effects are analyzed as well. At last, the results are compared with the experimental results with the same dimension and material. The analyses show that there has a good agreement with each other. So by this method, the design period of a contactless transformer will be shorter than befor
