This work pioneers the experimental acquisition of data relating to the heating effects of inter-bar currents and the frequency components of the main field rotating flux. Previous research in the field of inter-bar currents is reliant on theory and mathematical modeling. Yet, with the growing need for increasing machine efficiency; experimental application of conceptualized theoretical models of machine losses is paramount. Focusing specifically on inter-bar currents in a rotating stator induction machine revealed a correlation between the heat generated in the iron core and the presence of inter-bar currents. Using temperature sensing instrumentation, experimental data was gathered to determine the inter-bar current distribution along the length of the rotor bars during acceleration. Additionally, custom current transducers were implemented to directly measure the main field rotating flux. The results present a solid foundation for direct and indirect measurement of inter-bar currents. / Thesis / Master of Applied Science (MASc)
