| Abstract | In order to fundamentally overcome the fatal shortcomings of the existing artificial heart that it needs a passageway through the skin for the energy supply, and the energy conversion components giving out heat in the human body, we use the permanent magnet located outside human body as a non-contact driving device of a blood pump. Only the blood pump is implanted into the body and the remaining parts are outside the human body. The blood pump located in the body and the drive unit located outside the body have a pair of permanent magnet. When the active magnet outside of the body rotates, its magnetic field changes, so that the passive magnet in the body follows the rotating active magnet. Because the device's operating performance depends on the magnetic field distribution of the permanent magnets in space, so we have to do the study in-depth on the permanent magnet magnetic field distribution, as well as the interaction between the two permanent magnets. In this paper, we analyse and calculate the magnetic field distribution and drive-torque characteristics of permanent magnet using finite element method. This research on the drive mechanism and drive 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. |

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.
