  In this paper, the sub-region method is used to analyze the outer-rotor permanent magnet synchronous machine. In this method, based on hypotheses such as geometry, electrical and magnetic characteristics, the machine is divided into four sub-regions of groove, groove opening, air gap and magnet. Based on Maxwell's equations and considered assumptions, the governing partial differential equations for each sub-region are presented and solved analytically. In this paper, after calculating the air-gap flux density caused by the armature winding current and magnets with three patterns of radial, parallel and Halbach magnetization, the other main quantities of the machine are calculated accordingly. To validate the analytical model, the results obtained from MATLAB software are compared with the values obtained from the finite element method. Manuscript profile
