ABSTRACT CALCULATION OF CORE LOSSES OF A 6-PHASE INDUCTION MOTOR WITH 3RD HARMONIC CURRENT INJECTION BÜ / YÜ / KBAS, AfSin M.S., Department of Electrical and Electronics Engineering Supervisor: Prof. Dr. H. Bü / lent ERTAN January 2004, 106 pages The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to make good designs / it is necessary to obtain an accurate mathematical model for the loss calculation. The calculation of high frequency loss in this context presents a very difficult problem. In this thesis a modified version of a loss calculation model, which was developed in another MS thesis will be applied to a six-phase induction motor with third harmonic current injection.
