Abstract

This paper deals with the study of the cogging torque of a small two phases axial flux permanent magnet synchronous machine (AFPMSM). Analytical models of airgap permeance and of magneto-motive force (MMF) are proposed. In order to validate the developed analytical model, the obtained results are compared with that of a three dimensional (3D) finite element method (FEM) simulation of the motor in a special case. The cogging torque due to the permanent magnets (PM) is then estimated based upon the virtual works method. The influence of both magnetization distribution and shape of stator auxiliary poles on the cogging torque is evaluated by means of the developed analytical model
