Abstract | This paper documents a technique for deriving a steady-state, lumped-parameter model for capacitor-run single-phase induction motors. The objective of this model is to predict motor performance parameters such as torque, loss distribution and efficiency as a function of applied voltage and motor speed as well as the temperatures of the stator windings and of the rotor. The model includes representations of both the main and auxiliary windings (including arbitrary external impedances) and also the effects of core and rotational losses. The technique can be easily implemented and the resultant model can be used in a wide variety of analyses to investigate motor performance as a function of load, speed, and winding and rotor temperatures. Key to the practicality of this technique is the methodology presented in the paper for deriving model parameters based upon a simple set of measurements. This methodology takes advantage of the speed of digital computation which permits a search of parameter space to find a parameter set that best matches the measured motor performance. Finally, an example of the technique is presented based upon a 3.5 kW, single-phase, capacitor-run motor and the validity. of the technique is demonstrated by comparing predicted and measured motor performance.<> |

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.
