The disclosed is a rotating electric machine, comprising a magnetic iron stator and a surface permanent magnet type rotor, wherein a wire-winding axis and a rotating axial core of the stator cross each other orthogonally, and inner diameter portion of the stator is provided with an iron core having m wire-winding salient-poles arrayed circumferentially, and becomes gradually smaller from one side to another side in its axial direction, wherein the rotor has n poles with an arrangement that north poles and south poles are arrayed alternately in its circumferential direction, peripheral portion of the rotor becomes gradually smaller from one side to another side in its axial direction, and the stator and the rotor are engaged rotatably via a tapered air gap, wherein m is a positive integer of two or more, and n is a positive even number. |
