| Abstract | An ultrasonic linear motor using longitudinal and bending vibration double mode bolt-clamped Langevin type transducer was proposed and fabricated to achieve high speed. The elliptical trajectory of the driving tip was formed by exciting the longitudinal vibration and the bending vibration with 50 degree or -130 degree phase difference, which generate driving force and frictional force respectively. To achieve high linear speed, exponential shape transducer horn was adopted when the motor was designed due to its characteristic of magnifying vibration amplitude and vibration velocity. The classical theory of transducer horn was used to determine the transducer's longitudinal resonance frequency and its configuration dimensions. FEM method was employed to tune the longitudinal and bending vibration resonance frequencies. Typical output performances of the prototype are no-load velocity of 850 mm/s and maximum driving force of 50 N |

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.
