Abstract | This research deals with the optimization of a single-phase brushless DC motor (BLDCM) by substituting a commercial single-phase BLDCM for pump application in order to satisfactorily improve its efficiency regarding the required performance of a motor for pump systems (pump load 1,800 rpm, at 2 Nmm). The reliability of the results is verified between simulation and experiment using performance tests. In the sampling process, latin hypercubic sampling (LHS), the subject of many experiments, is usually used. However, this method requires a great deal of time and expense. This paper utilizes the table of orthogonal array in order to use the smallest possible number of experiments. In addition, a metamodel with second approximation polynomials is made using response surface methodology (RSM). The adjusted coefficients of multiple determinations which shows the reliability of the metamodel (multiobjective functions) is 100%. This result shows that the table of orthogonal array with the smallest number of experiments is suitable for sampling. The genetic algorithm (GA) is implemented to search for optimum solutions on the constructed metamodel which consists of two objective functions. With the optimal design set, predicted results of the GA are better than the generalized reduced gradient (GRG) algorithm. Nevertheless, verification results of the GRG are better than the GA. This result has an error within 1%. |

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.
