| Abstract | In general, a brushless dc (BLDC) motor is modeled by using a trapezoidal waveform as a back electromotive force (E.M.F.). It is a simple model with moderate accuracy. However, when BLDC motor operates in a high speed range where the back E.M.F. plays an important role to the characteristic of the machine, the trapezoidal back E.M.F. could lead to erroneous results. Although the finite element (FE) analysis can be applied for modeling with high accuracy, it takes so much time to simulate one operating point. Moreover, it is complicated and time-consuming to run in the dynamic operations. Therefore, it needs to be optimized between accuracy and time consumption. This paper presents a dynamic simulation model of BLDC motor with more accuracy comparing to the conventional simulation model. It uses the back E.M.F. and inductance which are obtained from the finite element method (FE method). The model was implemented in MATLAB/Simulink and PLECS program. In this work, the outer rotor BLDC motor for electric bicycles was used. The results of simulation model were verified by experiment. |

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.
