| Abstract | This paper provides a study of the main stator thermal barrier of an inner-rotor cylindrical brushless permanent magnet (BPM) synchronous servomotor with a concentrated winding configuration. Operating synchronous servomotors over continuous periods requires efficient thermal distribution of heat within the motor and also efficient dissipation of heat away from the motor. This is necessary to ensure that motors are running at cooler temperatures and hence provide optimum overall performance and better operating characteristics. Problems which may result if this is not achieved include demagnetising of the permanent magnets, burn-out of the windings, localised hot-spots and a consequent reduction in the operating life of the motor. Optimum performance and high efficiency requires investigation of the numerous machine parameters which necessitates a model that can be used to interpret how the characteristics interact and affect the output performance. The two motors used for this investigation were 12/10 slot/pole servomotors with concentrated winding configurations. Each servomotor was loaded and run up to the winding reference temperature at different speeds. The temperatures of the motor body parts for different wall insulation papers were recorded and compared with predicted values obtained from data using Motor-CAD software and an analytical model. Analysis and test results have been provided of the servomotor performance and thermal conductivity for two different main wall insulation materials. |

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.
