Zusammenfassung:	A motor rotor for a water pump, a water pump, and a pool circulation system are provided. The motor rotor comprises a hollow rotatable shaft having a first injection-molded part, and a magnet disposed circumferentially around a portion of the first injection-molded part. The first injection-molded part extends through an entire axial length of the magnet. The motor rotor also comprises an impeller integrally formed with the first injection-molded part, the impeller being located at an axial end of the hollow rotatable shaft. The motor rotor further comprises a shaft sleeve having a tubular shape located in the hollow rotatable shaft and extending substantially the entire axial length of the hollow rotatable shaft. The water pump has a simple structure, is easy to assemble, is less prone to generating noise during operation, and has a long service life.
