Abstract | A lot of saving energy policies are being globally instituted from the viewpoints of global warming and environmental preservation. Although a lot of effort has been put into improving industrial air conditioners, there are still efficiency problems with multisystem air conditioners in buildings where constant speed scroll compressors are used. We present the measurement results of a self-starting permanent magnet synchronous motor applied to a compressor drive. Compared with an isometric induction motor, efficiency improvements of 9% and 7% were confirmed for rated operation under 50 Hz and 60 Hz, respectively. The power factors also increased by 17% and 10% for the same rated operations, respectively. Moreover, the efficiency of the compressor equipped with the proposed motor was 9% and 7% higher than that with the conventional induction motor, under 50 Hz and 60 Hz operations, respectively. This result is consistent with the efficiency improvement of the proposed motor itself. |

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.
