Analysis of air gap flux density of 3Ph SQIM by 3D Maxwell and MMf permeance method under no load condition

This paper analyzes field distribution through the air gap ofa three-phase squirrel cage induction motor by the MMFpermeance method. The analytical approach considered primary armature reaction and multiple armature reaction effects, usually ignored at no-load operating conditions, with MMF harmonics, slot permeance harmonics, and saturation harmonics. A 3D model analysis of a squirrel cage induction motor using Ansys Maxwell 2019R1 has been performed to compare the analytical results.
