Abstract
An axial gap motor rotor opposes a stator in an axial direction. The axial gap motor rotor includes a rotor core and a magnet. The magnet is arranged on the rotor core. The magnet is configured so that one axial end includes magnetic poles that alternately change in a circumferential direction. The rotor core includes a base, which is located at a center in a radial direction, and radial extensions, which are extended from the base outward in the radial direction and arranged in the circumferential direction. The magnet is configured to at least partially overlap the radial extensions in the axial direction. The radial extensions are located to include a boundary of adjacent ones of the magnetic poles in the circumferential direction.
