Abstract :
An axial flux permanent magnet (AFPM) motor with dual stators and single rotor is studied in this paper. Due to its specific size constraints, both magnet radial length and axial thickness are investigated to improve the efficiency and anti-demagnetization capability, and to broaden flux weakening operation range as well. Then, parametric simulation on tooth width is adopted to verify the derived equations. The optimal model for two combinations of poles and slots are proposed and compared. Finally, the motor vibration modes are analyzed. Both theoretical analysis and three-dimensional (3-D) electromagnetic finite element analysis (FEA) are developed to verify the optimization.
