The following is a description of the principle and mechanism of action of the motor by analyzing the magnetic pole changes generated on the teeth of the stator and the acting force of the permanent magnet field on the rotor with respect to the respective phase changes of the axial field three-phase permanent magnet motor when the three-phase alternating current is in use, in combination with fig. 6 to 17.

In fig. 6 to 17, arrows on the respective windings indicate the current direction, and the current flows from the positive electrode +a to the negative electrode-a; the broken lines in each figure represent the direction of magnetic lines from north to south, and in order to show the magnetic lines of force when the three-phase alternating current is in each phase, we have intentionally drawn the rotor smaller to show the magnetic lines of force when in that phase. For theoretical analysis, the magnetic poles of the stator and the rotor can be equivalent to a certain point, and the method is commonly adopted as a common method in electrodynamics. In addition, for clarity, we have omitted from the corresponding figures for phases without current flow. For the case where one phase winding is energized on one of the teeth to produce a south pole and the other phase winding is energized to produce a north pole, which appears in the figures, we mark the one tooth with a small circle, such as teeth 2,5,8 and 11 on fig. 5, which we call electrical losses (power losses). To facilitate analysis of the stator field variation, the magnitude of the normalized field strength is indicated on the teeth and a value of 0.866 is indicated at 0.9. In fig. 6 to 23, the so-called "left" and "right" are defined in terms of left and right positions of the center of the armature tooth 6 so as to unify the directions of observation.
