| Abstract | In this paper an accurate and fast thermal equivalent circuit (TEC) model of an interior permanent magnet synchronous machine (IPMSM) is presented. This model is capable of simulating transient thermal effects. The key parameters of the presented model are the heat transfer coefficients which consider heat transfer from the solid to the fluid regions, and vice versa. An innovative parametrization method is introduced to determine these coefficients: First, the heat flows between adjacent regions are calculated by utilizing a 3D computational fluid dynamics (CFD) simulation. Second, the heat transfer coefficients of the TEC model are determined by minimizing an objective function which takes the heat flow deviation between the TEC model and the CFD model into account. The TEC model parametrized this way can be used to predict the thermal behavior of a permanent magnet machine drive under varying speed and torque conditions. The validity of the TEC model is verified by means of measurement results. For this purpose a prototype of the investigated IPMSM is equipped with temperature sensors in the stator, rotor, and cooling circuit, respectively. |

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.
