| Abstract | A study of the design, fabrication and operational characteristics of a Hoop Energy Storage System (HESS) has been done. For the magnetic levitation of Nd-Fe-B permanent magnet, the magnetic force calculation and dynamic analysis of the rotational stability were included in the design and operation of HESS. 2564 Nd-Fe-B magnets which has the dimension of 2 in./spl times/2 in/spl times/1 in were assembled for the levitation of a 3.7 ton carbon fiber composite hoop. A computer simulation of rotation under magnetic force and torque due to both the vertical stabilization magnetic set and the radial stabilization magnet set showed that the rotation of the hoop's spin axis induced by the torque of the levitated rotor magnets reduces the additional active control. The fabrication of a 6 m-diameter carbon fiber composite hoop was completed and the ANSYS code was used to study its stress analysis. The study showed that the strength of the hoop material is high enough for the 600 MJ-energy storage. A performance test, of the HESS at a low speed rotation is reported. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
