Abstract In order to study the influence of eccentricity on the force of axial flux permanent magnet motor, an analytical model of the air gap magnetic field in the ideal state is established. The slot is also accounted for by introducing the air gap permeability function. The influence of the air gap magnetic field; through the analysis of the eccentric state of the axial flux permanent magnet motor, an analytical model of the air gap magnetic field in the eccentric state was established, and the accuracy of the analytical calculation model was verified by the finite element method. Based on the analytical method, calculation model of the unbalanced magnetic force of the axial flux permanent magnet motor under eccentric state is constructed, and the unbalanced magnetic force is calculated and analyzed. Regardless of static eccentricity or dynamic eccentricity, the amplitude of unbalanced magnetic force gradually increases with increasing eccentricity. Under static eccentricity, the unbalanced magnetic force does not change with time; under dynamic eccentricity, the unbalanced magnetic force changes periodically.

Key words： Axial magnetic flux permanent magnetic motor air gap flux density eccentricity unbalanced magnetic force
