Abstract: A liquid pump includes a motor and an impeller. The motor includes a stator, a rotor, a base body and a shaft sleeve unit supporting the rotor for rotation. The shaft sleeve unit includes a fixing member fixed in the base body, a bearing received in the fixing member and surrounding the rotary shaft, and a resilient buffering member disposed between the fixing member and the bearing. The impeller is coupled to the rotor.

Abstract: A motor (10) and a pump having the motor are provided. The motor (10) includes a stator (14) and a rotor (16) rotatable relative to the stator (14). At least one of the stator (14) and the rotor (16) has a magnetic core (20) and a winding (22) wound around the magnetic core (20). The magnetic core is mounted to a base body (18). The base body (18) has at least one recess (54) for receiving debris produced by mutual friction between the magnetic core (20) and the base body (18).

Abstract: A liquid pump includes a housing, a motor fixed in the housing, and an impeller driven by the motor. The motor includes a stator and a rotor rotatable relative to the stator. The impeller is connected to a rotor of the motor. The housing includes a guide wall surrounding the stator, and a guide face extending outwardly from an outer surface of the guide wall to guide a liquid flowing to the guide wall to flow in a direction away from the stator, thus ensuring the electrical safety of the liquid pump.
