When the rotor is manufactured, through an injection molding process, the magnetic ring 120 and the rotating shaft 110 are fixed through a mold, then molten plastic is injected between the magnetic ring 120 and the rotating shaft 110, so that the magnetic ring 120 and the rotating shaft 110 are integrally injection-molded, subsequent assembly procedures are reduced, the assembly efficiency of the rotor is improved, meanwhile, the structure of the rotor is more compact, the reduction of the whole volume of the rotor is facilitated, the structural stability of the rotor can be stronger, and the magnetic ring 120 is prevented from being easily loosened in the working process.
In the related art, a stator assembly of a traditional circulating pump is assembled in a shell, a shielding cover is arranged in the middle of the stator assembly, a rotor is installed in an inner cavity of the shielding cover, and a drainage channel is arranged between the shell and the shielding cover, so that condensed water or vapor is prevented from being immersed into or even accumulated on a conductive part of the stator. Therefore, in some embodiments of the present invention, the stator 180 is a plastic-coated stator, so that the waterproof performance of the stator 180 is better, the risk of soaking the conductive part of the stator 180 is reduced, a drainage structure is not required, the manufacturing cost is reduced, the number of parts can be further reduced, and the assembly efficiency is improved.
It should be noted that, when the rotor works, the rotating shaft 110 drives the impeller 310 located in the pump chamber 320 to rotate, the shield casing 150 contains liquid, the rotor is immersed in the liquid, and in order to reduce the impurities in the liquid from settling in the shield casing 150, referring to fig. 2, in some embodiments of the present invention, the rotating shaft 110 is provided with the first passage 112 penetrating axially, and one end of the rotating shaft 110 extends into the pump chamber 320 and is connected with the impeller 310.

Of course, the second passages may be provided in plural, and the plural second passages are arranged at intervals along the circumferential direction of the plastic-coated member 130, so that the liquid flows more smoothly between the pump chamber 320 and the inner space of the shield cover 150, the deposition of impurities in the liquid in the shield cover 150 is further reduced, and the smoothness of the rotation of the rotor is favorably maintained.
It can be understood that the rotor has a relatively large rotational speed and thus a relatively large moment of inertia when in operation. Since the magnetic ring 120 is fixed on the outer wall of the rotating shaft 110, when the rotating speed of the rotor is high, the magnetic ring 120 is easy to loosen relative to the rotating shaft 110, and therefore, referring to fig. 5, in some embodiments of the present invention, the outer wall of the rotating shaft 110 is further provided with a sunken groove 115, when the magnetic ring 120 and the rotating shaft 110 are integrally formed through the plastic-coated piece 130, a part of plastic forming the plastic-coated piece 130 is embedded in the sunken groove 115, so that the clamping force between the plastic-coated piece 130 and the rotating shaft 110 is greatly improved, and thus the magnetic ring 120 can be more stably installed on the rotating shaft 110, the magnetic ring 120 is prevented from moving relative to the rotating shaft 110, and the stability of the rotor structure is improved.

The sleeve 140 can limit the magnetic ring 120 in the circumferential direction, so that the stress condition of the magnetic ring 120 is improved, the cracking or falling phenomenon of the magnetic ring 120 is reduced, and even if the magnetic ring 120 cracks, the magnetic ring 120 cannot directly fall off due to the limiting effect of the sleeve 140, and the after-sale related maintenance is facilitated. Specifically, the sleeve 140 may be a steel sleeve, which has good ductility and can better wrap the periphery of the magnetic ring 120, so as to limit and fix the magnetic ring 120. Of course, the magnetic ring 120 may be made of other suitable materials.

Certainly, during installation, the rotating shaft 110 may also be fixed, then the flat hole 311 is aligned to the flat section 113, and then the impeller 310 is sleeved on the rotating shaft 110, so that the rotating shaft 110 is inserted into the flat hole 311, thereby implementing the installation connection of the impeller 310 and the rotating shaft 110. Specifically, the thickness of the relative pivot 110 main part of thickness of flat position section 113 is little, and the cross section of flat position section 113 is rectangular shape approximately for flat position section 113 can the joint in the flat hole, thereby drives impeller 310 and rotates.
