Abstract | There are benefits if copper windings are replaced with aluminium in applications which are cost and mass sensitive, such as automotive traction; these include the low cost of aluminium, low mass of aluminium and the ease of motor recycling at end of life. However the relatively low electrical conductivity of aluminium compared to copper needs to be overcome. Pre-compressed motor coils have been shown to produce very high fill factors (>75%), reducing DC winding losses, therefore enabling the use of aluminium conductors. However the single stranded conductors used can be prone to high AC losses due to skin and proximity effects. Therefore a method of manufacture of pre-compressed coils made from stranded / Litz wire is needed, allowing AC losses to be reduced to low levels. This paper describes the development and test of stranded, pre-compressed aluminium coils which have been developed for use in an automotive traction application. |

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.
