Abstract | In this work, we introduce a newly developed passive and frictionless diamagnetic contactless suspension rotor with electrostatic glass motor. A 20 mm diameter disc-shaped rotor comprised of pyrolytic graphite with glass is fabricated. The rotor is diamagnetically and passively levitated by an array of Nd–Fe–B magnets at room temperature without any energy supply. To realise the rotating function, a 700 V high voltage electrostatic glass motor is designed and arranged in the levitation air gap between the rotor and the magnets. To install the stator in this narrow air gap, we fabricated the stator using a flexible printed circuit with 100 μm thickness. The newly developed system is more compact, stable and of high performance. The maximum speed has been improved doubly to 300 rpm in atmosphere. We intend to draw attention to this uncommon levitation and to show that it could be used for micro-mechatronic system. |

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.
