Abstract:
An axial gap motor includes a stator having stator teeth, and also includes a rotor opposed to the stator with a gap in an axial direction of the stator. Each of the stator teeth includes a stator tooth body, a stator tooth end joined to at least one axial-direction end of the stator tooth body, and a stator coil disposed around the stator tooth body. The stator tooth body includes a wound core comprised of a multi-layered amorphous foil strip winding. The stator tooth end is formed by a compact including a powder magnetic core, and the stator tooth end includes a surface opposed to the rotor. A cross-sectional area of the stator tooth end perpendicular to an axis of the amorphous foil strip winding is larger than a cross-sectional area of the stator tooth body perpendicular to the axis of the amorphous foil strip winding.
