| Abstract | In this study, we investigate the additional harmonic losses of induction motors driven by PWM inverters from both results of experiments and calculations. In the experiments, the additional loss caused by the inverter carrier is obtained by subtracting the total input of the motor driven by a sinusoidal power supply from that of the motor driven by the inverter. In the calculation, a combined 2-D and 1-D finite element method is applied in order to take into account the skin effect in electrical steel sheets used for the core. Then, the components of the additional motor loss are individually calculated according to their origins. Both the experimental and calculated results show that the total additional loss caused by the inverter decreases with an increase in the switching frequency and that the total additional loss does not depend on load conditions. These tendencies are exactly the same as that described in IEC/TS 60034. On the other hand, the finite element method reveals the variation in each loss component with switching frequency and load conditions. It is concluded that the variation in the additional loss with the switching frequency is mainly attributed to the variation in the core loss. In addition, the ratio of harmonic copper and rotor cage losses increase whereas that of harmonic core loss decreases with load because of an increase in the magnetic saturation at the rotor surface. |

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.
