Abstract: In this paper a new method is presented to couple an analytical magnetic field solution of the air-gap of an induction machine with magnetic equivalent circuits method used to model the rest of the machine. The proposed method eliminates the need for complex static and dynamic mesh generation process in the air-gap. Therefore, the modelling of rotor motion becomes simpler and more accurate.
