Abstract | To overcome the voltage regulation difficulty of permanent-magnet synchronous machine (PMSM), a hybrid excitation synchronous machine (HESM) with the radial structure of magnetic shunting type was designed. The magnetic shunting was exploited to adjust the air-gap magnetic field of the HESM by adjusting excitation current. The paper describes the machine's structure and principle. The concepts of the magnetic shunting point, the magnetic non-shunting point and the load balanced point were discussed. The air gap flux at magnetic shunting point and the magnetic non-shunting point were precise analyzed. The two-dimensional finite-element method (FEM) was exploited to count the positions of magnetic shunting point, the magnetic non-shunting point and the load balanced point. The theoretical analysis and experimental results show that the air gap flux of machine is lowest at magnetic shunting point and the air gap flux of machine is biggest at magnetic non-shunting point. The output voltage of machine can be kept constant by adjusting the excitation current when the power factor and the load changes. |

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.
