| Abstract | The interior permanent magnet (IPM) machine is considered to be the one of the most efficient electrical machine. The high efficiency along with good performance characteristic makes them suitable for drive with wide speed range. The conventional IPM machine has almost nil or very little field weakening range. Many attempts have been made to improve the range by modification of rotor configuration. In this paper, different types of rotor configuration of IPM machine that is suitable for flux weakening operation has been reviewed. A new rotor design of segmented magnet has been studied by finite element (FE) analysis. The result of FE model of segmented magnet rotor and a conventional rotor of IPM machine has been compared and discussed. In the new design an improved flux weakening aspect has been noticed. Since the new design does not need any special construction effort, it could be a better solution for IPM rotor configuration suitable for field weakening operation. |

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.
