| Abstract | In this paper, we analyze and calculate the magnetic field and eddy current distribution and electromagnetic torque characteristics and eddy current loss of permanent magnet of the non-contact driving device for the blood pump of artificial heart using finite element method. Through the analysis, we know that the driving device can deliver the enough torque when the spacing distance between the active and the passive magnet axis is 120 mm. This torque fully meets the energy transfer request of artificial heart blood pump. By comparing the calculating results of magnetostatic field and time-dependent magnetic field, we know that the influence of the eddy current on the electromagnetic torque can be ignored in normal working of non-contact driving device. This research on the driving characteristics of the non-contact permanent magnet power transmission system has laid a theoretical foundation for the optimal design of an artificial heart with the permanent magnet driving device. In addition, the research's findings can also be used for the reference of other non-contact permanent magnet gear drive problems. |

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.
