Outline of Final Research Achievements

In this research, to investigate the reduction of stray load losses in induction motors using the magnetic field analysis taking account of the laminated structure and the eddy current in steel plate of core, first, this homogenization technique is expanded to apply induction motors in which fluxes rotate. Then, a practical method of coupled 2-D and 3-D eddy current analyses to evaluate inter-bar current losses in cage induction motors is also developed. Next, a method to evaluate iron loss taking account of stress due to electromagnetic force, magnetostriction, and shrink-fitting is also developed. Finally, the magnetic field analyses of actual induction motors taking account of laminated structure and slot harmonics are carried out to evaluate stray load losses. It is shown that flux concentration in the surface of core causes stray load losses.
