For example, Publication (Announcement) No.: CN216691486U discloses a DC brushless silent water pump rotor. In this scheme, the magnetic ring is set as a split structure, which causes the magnetic ring and the impeller to be assembled out of center. It is easy to jitter during operation, and the silent effect is poor, which reduces the stability of the impeller rotation. To this end, a DC brushless silent water pump rotor is proposed.
