a rotor;

a radial stator facing an outer circumference of the rotor; and

a first axial stator facing a first axial end side of the rotor and a second axial stator facing a second axial end side of the rotor;

wherein the rotor comprises:

a plurality of conduction bars arranged in radial and axial directions, corresponding to the radial stator and the first and second axial stators; and

a plurality of end-rings electrically connecting the plurality of conduction bars and spaced from each other in axial directions;

wherein the first and second axial stators are disposed on an inner side, which is based on the radial direction, of the radial stator;

wherein each of the first and second axial stators is surrounded by an axial end coil of the radial stator and outwardly faces the axial end coil, in the radial direction; and

wherein each of the first and second axial stators is disposed inward in the axial direction with respect to the axial end coil of the radial stator so each of the first and second axial stators does not protrude in the axial direction with respect to the axial end coil of the radial stator;

wherein each of the first and second axial stators includes a stator core providing a magnetic flux path and an axial coil wound on the stator core; and

wherein at least a portion of the axial coil is disposed in a gap formed in the radial direction between the axial end coil and the stator core.
