ABSTRACT:
The axial gap type motor according to the present invention is provided with: a rotor and a first stator and a second stator, wherein the first and second stators includes an annular back yoke and a plurality of teeth which is provided on the annular back yoke at predetermined intervals in a peripheral direction so as to protrude toward the rotor in the direction of the rotation axis; the peripheral pitch of the plurality of teeth of the first and second stators are equal to each other; and in a case where the first stator and the second stator which sandwich the rotor therebetween in the direction of the rotation axis are seen from one side in the direction of the rotation axis, facing surfaces of the teeth of the first and second stators which face to the rotor are formed so as not to overlap completely each other.
