Summary:An axial motor of the present invention includes a rotor 2 arranged between a pair of stators with coils. In the rotor 2, a plurality of permanent magnets 23 sandwiched between pairs of first magnetic materials 21 and a plurality of second magnetic materials 22 are alternately arranged in a rotation direction while gaps 24, 26 and 27 are provided therebetween. Since the permanent magnets 23 are sandwiched by the first magnetic materials 21 in the thus constructed axial motor, a field-weakening control can be performed. Since the second magnetic materials 22 are provided, a reluctance torque can be generated. Further, since the gaps 24, 26 and 27 are provided, more magnetic fluxes generated from the permanent magnets 23 can be caused to flow toward the coils. Therefore, the thus constructed axial motor can achieve a higher output (higher torque) and higher efficiency (miniaturization).
