However, the inventor of the present application finds that, in general, in the current domestic permanent magnet synchronous direct-drive motor, because the rotating speed is low, the cooling effect is not good by adopting a mode that the rotor is provided with a fan, and the water cooling mode has a complex structure and needs to solve the problem of water source.
Specifically, for some permanent magnet synchronous direct-drive motors with large volume, if an axial-flow fan is adopted, because the motor has large volume, the axial-flow fan needs to select blades with large outer diameters and a long air path, so that the increase of the overall dimension and the power of the motor of the axial-flow fan is easily caused, and the design and the use of the motor are not facilitated; secondly, if the large permanent magnet synchronous direct drive motor adopts a water cooling structure, water source supply is needed, so that the cooling system is complicated, and the corrosion resistance of the motor can be reduced.
