The development and design of electromagnetic device reflects a complex process. Originating from an initial idea, the construction runs through different phases. This procedure is terminated when a final concept is selected and considered to be optimized, subject to various targets and constraints. As a whole, the task of the design engineer is to find solutions for technical problems. On the way to the final physical and technical product, certain aspects have to be considered. Technological and material questions, cost effectiveness and ecological constraints have to be taken into consideration. A subset of the boundary conditions controls the feasibility of the final design. With emphasis on electromagnetic devices, Fig. 1 shows a simplified scheme of the interdependencies of targets and constraints. This simple pattern shows that the design process is strongly dependent on the experience of the engineer and reflects an optimization procedure with often contradictory aims. Therefore, the necessity of a systematic design using engineering tools is obvious . In this paper, solution strategies using modern numerical methods to accelerate and ensure a high-standard technical product in an overall design process are discussed. A numerical optimization tool is used to automate the design process to obtain an automated optimal design according to given constraints and limitations. Practical design examples conclude the paper and demonstrate the behaviour of the strategies and methods used. The combination of numerical field computation and optimization methods produces an automated and structural development procedure and uses the analysis tools in a powerful design methodology with a general application range.
