Abstract: An axial motor includes a fastening plate and a plurality of magnetic cores. The plurality of magnetic cores are spaced apart around the inner shaft sleeve. A magnetic core end part of the magnetic core covers a part of an end surface of a magnetic core winding part of the magnetic core, and an end surface, of the magnetic core winding part, that is not covered by the magnetic core end part forms a step surface. The fastening plate is fastened to an end surface of the inner shaft sleeve. The fastening plate includes an accommodating groove that is concave relative to the end surface of the inner shaft sleeve. A plurality of magnetic core accommodating holes are provided in the accommodating groove. The plurality of magnetic core accommodating holes respectively correspond to magnetic core end parts that accommodate the plurality of magnetic cores.
