Abstract | This paper presents the experiment results of the magnetic suspension in a bearingless brushless DC motor to apply in small liquid pumps. The bearingless motor structure, the principle of the suspension force generation and the magnetic suspension control strategy in the bearingless brushless DC motor have been proposed by the author. A prototype bearingless brushless DC motor has been designed based on the computed results by Finite Element Method (FEM) to apply a small liquid pump. It is confirmed by the experiments using the prototype machine that the rotor is successfully suspended without mechanical contact when it drives a liquid pump at the maximum rotational speed of 2,200 r/min and the maximum fluid flow of 8.2 l/min. This result shows that the proposed bearingless brushless DC motor is enough suitable as the drive for the small liquid pumps. |

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.
