To analyze the transient state of an induction motor, there have been studies for using the magnetic equivalent circuit method (MECM) instead of the time differential finite-element method, MECM which analyzes magnetic equivalent circuits after converting each part of an electric machine into the magnetic circuit elements. has the merits of short calculation-time and comparatively accurate results. To analyze an electric machine with MECM, we have to replace stator and rotor with the magnetic elements and express the air gap, where electromechanical energy conversion takes place, with the permeance. So in this paper, to analyze an Induction Motor with MECM, we express the magnetic equivalent circuit as algebraic equations and then as the matrix for solving easily them.
