| Abstract | To enhance the power density of five-phase induction motor system, the structure with concentrated full-pitch windings is adopted, and then the five-phase motor system is drove by a non-sinusoidal power supply with third-harmonic injection. By dual-plane rotation transformation, the mathematic models in two orthogonal space planes, d1–q1 and d3–q3, were deduced. The magnetic fluxes in the fundamental and third-harmonic space were oriented on the d1 and d3 axes, and the corresponding equations of rotor field-oriented control were obtained. To satisfy the requirement of a quasi-square air-gap flux, the direct and quadrature current components in the third-harmonic plane as non-linear functions of the fundamental components are calculated. On the basis above, the field-oriented vector control method for a five-phase induction motor with the third-harmonic current injection was proposed. Finally, simulation by MATLAB/Simulink and experiment is implanted on the five-phase induction motor. The results indicate that the air-gap magnetic field gets improved, and the power density of five-phase induction motor is enhanced without any increase of power switch capacity and machine size. |

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.
