This type of motor not only greatly improves power density, but also extends motor life and reduces maintenance costs due to its excellent heat dissipation effect.

It includes a first shell, a second shell, a stator winding and a rotor, and stator windings are arranged on both sides of the rotor, wherein the outer side of one stator winding is equipped with a first shell, and the outer side of the other stator winding is equipped with a second shell; the interior of the first shell and the second shell both include an outer water channel cover plate, an outer ring water channel cover plate, an outer water channel shell, an inner water channel outlet side shell and an inner water channel inlet side shell. The present invention provides a stator water-cooling structure and cooling control method for an axial flux motor, which can select a higher heat load by improving the internal heat dissipation of the stator winding, permanent magnet and axial flux motor; the requirements for water tightness are low, and leakage is not easy to occur; the inner water channel and the outer water channel can be controlled separately, so that the thermal management of the motor is more flexible and the energy consumption is lower.

[0004] After long-term use, the sealing performance of the connection between the water pipe and the inlet and outlet pipes of the existing motor will gradually deteriorate, and water leakage will occur at the connection. If water drips directly onto the motor casing, it will cause certain damage to the motor over a long period of time. Therefore, a water-cooled stator motor structure is required to ensure this.
