Abstract | Finite element method (FEM) reveals to be one of the most valuable tools in electric machines design as it accurately takes into account non-linear materials and complex geometry. However, this is by nature an analysis tool, which makes the design procedure very iterative, hence time consuming. Furthermore, the final result is quite uncertain. This main drawback can be eliminated by combining FEM with response surface method (RSM). RSM is a statistical tool to derive experimentally an analytical relationship between a response and some input variables. It is particularly suitable when the underlying phenomenon linking them is not well known or too complex to be modeled mathematically. The relationship is derived by regression from a small number of observations of the response that can be provided by FEM. Genetic algorithm (GA) can then worked directly on this model to optimize the device with a decrease in computational cost. This paper presents the combination of FEM, RSM and GA to optimize the rotor geometry of an interior permanent magnet synchronous motor for fast and accurate design procedure. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
