1. A motor comprising:
a rotor rotatable about a central axis extending in an axial direction; and
a stator that includes a stator core having an annular shape surrounding the central axis,
wherein the rotor includes:
a cylindrical portion that is arranged on a radially outer side with respect to the stator and extends in the axial direction;
a first plate portion that is arranged on a first axial side with respect to the stator and expands radially inward from a first axial end of the cylindrical portion;
a second plate portion that is arranged on a second axial side with respect to the stator and expands radially inward from a second axial end of the cylindrical portion; and
a hole penetrating at least one of the cylindrical portion, the first plate portion, and the second plate portion, wherein
the hole includes at least one rotor hole of a first rotor hole penetrating the first plate portion in the axial direction and a second rotor hole penetrating the second plate portion in the axial direction,
at least one plate portion of the first plate portion and the second plate portion has a wall surface facing a circumferential direction, and
the wall surface is arranged at an end, closer to the stator in the axial direction, of the at least one plate portion, extends at least in the radial direction, and is connected to the at least one rotor hole,
the at least one plate portion has a bottom surface facing the axial direction, and
the bottom surface is arranged at an end, closer to the stator in the axial direction, of the at least one plate portion, extends in the circumferential direction from the wall surface, is connected to the at least one rotor hole, and is more inclined to a side opposite to the stator in the axial direction as approaching the at least one rotor hole in the radial direction.
