Abstract:
This paper introduces a structured approach to the multi-objective optimization of electrical machines. The process covers the key steps: defining the problem, identifying the most relevant key performance indicators and constraints, setting the design space, formulating objective functions, and then modeling and evaluating the results. Using a permanent magnet synchronous machine as an example, the study shows that it is possible to achieve up to 9% higher output power or reduce the overall cost by as much as 18% compared with the reference design. These results highlight the value of the proposed method and provide a solid basis for choosing the most suitable design for a given application.
Keywords:
