Abstract
An axial flux motor structure uses a magnetic levitation force and a rotational force and includes a stator configured so that a coil unit is wound therearound, a permanent magnet unit configured to generate an air gap by generating a repulsive force with the coil unit, and a rotor configured to be fastened to the permanent magnet unit and coupled to a rotary shaft to rotate. A ratio of the number of slots of the stator and the number of poles of the rotor is 3:1.
