Problems solved by technology

However, during the use of the existing disc motors, the stator assembly is the main heat-generating part of the disc motor. The stator assembly is mainly composed of the stator core and the winding coil. The winding coil is the main heating element, so the temperature near the winding coil is usually They are all the highest, so it is necessary to focus on cooling the position of the winding coil, but the existing cooling channel located in the water-cooled end cover does not take this into consideration, resulting in the process of cooling water flowing through the cooling channel. The temperature around the winding coil cannot be cooled well, resulting in poor overall heat dissipation effect of the disc motor. At the same time, during the heating process of the winding coil, the part close to the inner circle of the stator core is denser, and the temperature is usually higher than that of the winding coil located in the stator. The temperature of the outer ring of the iron core is high, so it is also necessary to consider the characteristics of the lower temperature of the outer ring of the stator assembly and the higher temperature of the inner ring, so it is necessary to propose a new energy intelligent drive motor cooling system
