Patent ID: 7977843

Claim:
An axial gap motor comprising: a rotor rotatable around a rotation axis; and a first stator and a second stator arranged so as to sandwich the rotor therebetween in the direction of the rotation axis, wherein: each of the first and second stators include an annular back yoke and a plurality of teeth, wherein the teeth are provided on the annular back yoke at predetermined intervals in a peripheral direction of the back yoke so as to protrude toward the rotor in the direction of the rotation axis; a peripheral pitch of the plurality of teeth of the first stator and the peripheral pitch of the plurality of teeth of the second stator are equal to each other; and wherein the first stator and the second stator, which sandwiching 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 stator and facing surfaces of the teeth of the second stator are arranged so as not to overlap completely each other, and wherein: a peripheral width of the teeth of the first stator is greater than a peripheral width of the teeth of the second stator; and the width of a first slot, wherein the first slot is the space between adjacent teeth in the peripheral direction of the first stator is smaller than the width of a second slot, wherein the second slot is the space between adjacent teeth in the peripheral direction of the second stator.
