Abstract:
An axial gap motor includes a rotor and a stator disposed to be separated with a gap from the rotor in a direction parallel to a rotation axis of the rotor. The stator includes a bobbin housing a coil and a core provided on an inside of the bobbin and configured by a plurality of magnetic sections. A first magnetic section among the plurality of magnetic sections is in contact with an inner peripheral wall of, among side portions of the bobbin, a first side portion opposed to a side portion of a bobbin on one side adjacent to the bobbin. A second magnetic section among the plurality of magnetic sections is in contact with an inner peripheral wall of, among the side portions of the bobbin, a second side portion opposed to a side portion of a bobbin on the other side adjacent to the bobbin. A void portion is present between the first magnetic section and the second magnetic section.
