| Abstract | The vibration in induction motors is due to mechanical and electrical forces existing during the motor operation. The vibration monitoring can help to prevent wear in motors, to increase its efficiency and lowering maintenance costs. Through knowledge and accurate diagnostic procedures, it is possible to detect the cause of the vibration. This paper presents the vibration measurement analysis in the induction motor running at no-load condition using a biaxial optical fiber accelerometer. The sensor is positioned on the induction motor, and the acquired data compared with the one from a capacitive sensor. Changing the power supply frequency from 10 to 60 Hz a higher SNR was observed for both directions on the optical sensor data. The characteristics of the optical sensor, immunity to electromagnetic interference and high sensitivity, 87.848 pm.g-1 and 92.351 pm.g-1 for two directions and independent directions, favors its use for monitoring vibrations in electrical machines. The results indicate a relation between deterioration and mechanical vibration and, thus, providing the motivation for additional study and a basis for future applications. |

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.
