Abstract | A two-dimensional analytical model is presented for predicting the air-gap magnetic flux density due to the permanent magnet (PM) and armature currents in brushless surface inset PM (BSIPM) machines. The virtual current theory is used to model the effects of the stator slots and rotor grooves. In this approach, the BSIPM machine is initially modelled as a machine without any stator slot and rotor groove, and the rotor groove and stator slot effects are modelled by a set of surface currents. By extracting the governing Laplace and Poisson equations and applying the boundary conditions, the magnetic flux density due to the PM and armature current is obtained in different parts of the machine. The accuracy of the proposed analytical model is confirmed by comparing its results with those of the finite-element method and experimental results. The proposed model is also compared with the subdomain analytical model in terms of computational speed and accuracy. |

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.
