| Abstract | Open-loop operation mode is often applied in sensorless Permanent-Magnet Synchronous Motors (PMSM). The stator windings are supplied in a proper proportion to the desired working frequency in this mode without the knowledge of rotor position. However, the rotor synchronization will be destroyed once the ratio is inappropriate. In order to analyze the reliabilities of the open-loop operation mode, a dynamic equation is established to represent the synchronism error between the rotor and the stator. The stability of the open-loop control mode is analyzed based on the indirect Lyapunov theory. Theoretical analysis indicates that the open-loop control mode is stable only when the stator current phase lags appropriately behind the back electromotive force (EMF). The result of an experiment on a certain PMSM verifies the effectiveness of the theory. |

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.
