| Abstract | High torque as one important characteristic of longitudinal-torsional hybrid transducer-type ultrasonic motor (HTUSM) is mainly caused of discontinuous-surface-connect mode between the stator and the rotor which is different from the many-point-connect mode of traveling wave motors. Therefore, it is important that one connect friction model is proposed to analyze this connect mode between the stator and the rotor. In this paper, according to the adhesion theory of friction, an advanced equivalent circuit of the motor which contains both the longitudinal vibrator and torsional vibrator is proposed. Based on this model, a design method of a longitudinal-torsional hybrid transducer-type ultrasonic motor (HTUSM) aimed at practical uses of the motor is presented. All factors that influence the mechanical characteristics are analyzed, and low-efficient of this type motor is explained. Based on this study, mechanical characteristics of the motor such as the maximum torque, efficiency and the no-load speed and preload are determined. |

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.
