| Abstract | Applications such as emergency breakers, protective devices in explosive environments, emergency exit openings, etc., fall into a broad category that can be grouped under the general term transient applications. There are cases in which a motor is to be operated only for a short duration. The use of standard procedures to select or design a motor for these transient applications, will most probably result in an over dimensioned and an over-sized motor. An alternate approach is hence required. This paper provides guidelines on how to select an off-the-shelf motor and when necessary, on how to design a new motor for such applications. A design example is also provided, and the analysis is verified by building and testing a prototype. It is found that with some derating calculations, an off-the-shelf selection can yield an induction machine solution. However, there may be cases where the selection is not compact enough. In such cases a new permanent magnet motor design is required and a BLDC motor is a realistic choice from a cost perspective. It is found that for such applications, the most critical design factor is to avoid magnet demagnetisation. The thermal loading is not a design factor owing to the very small application times involved. However, a thermal check on the obtained design is always advisable. |

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.
