Abstract: The present disclosure provides a cooling structure, a stator, an axial flux motor and an assembly method thereof. The cooling structure includes a cooling disc, which includes a rotor-facing surface, a stator-facing surface and several stator sleeve holes which run from the rotor-facing surface to the stator-facing surface. A flow channel is further arranged between the rotor-facing surface and the stator-facing surface, and surrounds each of the stator sleeve holes. The cooling disc can be built into the motor and arranged between the stator and the rotor. A cooling medium is introduced into the flow channel to transfer the heat of the rotor and the stator through the flowing cooling medium. Compared with conventional frame water channel arrangement, the heat transfer path between the rotor and the stator and the cooling structure is shortened, effectively improving the heat dissipation effect to ensure the reliable operation of the motor.
