An axial flux motor is disclosed, with at least one rotor, with at least one stator that has a stator yoke and at least one stator tooth made of a soft magnetic powdered material, which stator tooth has a tooth neck and a tooth head that adjoins the tooth neck and constitutes the pole face of the stator tooth, and with a fastening means that comprises at least one mechanical connecting element, which connecting element fastens the stator tooth to the axial flux motor. In order to embody this in a durable way, it is proposed for the stator tooth to have a fastening opening, which, starting from the pole face of the stator tooth, passes through its tooth head and tooth neck, with the mechanical connecting element being accommodated in the fastening opening in countersunk fashion relative to the pole face.
