Axial flux motor and electrical product
Embodiments of the disclosure provide an axial flux motor and an electrical product. The motor includes a rotor which rotates with a central axis as a center, and a stator which is disposed opposite to the rotor in an axial direction and has a plurality of stator units, the plurality of stator units being disposed around the central axis. The stator unit includes a core unit formed by a core piece, and a coil unit formed by a wire wound and disposed around the core unit. A height of the core unit in the axial direction is less than or equal to a height of the coil unit in the axial direction. With the embodiments of the disclosure, the dependency between the coil and the core in design and manufacture can be reduced, and the degree of design freedom can be improved.
