An electrically driven pump is provided, which includes a rotor assembly. The rotor assembly includes an impeller, a rotor and a shaft sleeve assembly. The impeller is arranged on one end of a shaft sleeve, and the rotor is arranged on another end of the shaft sleeve away from the end on which the impeller is mounted. The rotor includes a rotor core, a permanent magnet and a shield. The permanent magnet is arranged around an outer peripheral surface of the rotor core and fits the outer peripheral surface of the rotor core. The shield is fixed to the shaft sleeve, and an accommodating portion configured to accommodate the rotor core and the permanent magnet is formed between the shield and the shaft sleeve. The electrically driven pump has a simple structure and is easy to manufacture.

Electrically driven pump and method for manufacturing the same

An electric pump is provided according to the application, which includes a housing, a shaft, an impeller, a rotor assembly, a stator assembly and an inner chamber. The shaft, the impeller and a rotor are arranged in the inner chamber. The housing includes a first housing, a partition and a second housing, and the partition divides the inner chamber into a wet chamber and at least one dry chamber. The partition includes a first side wall, a first bottom, a second side wall and a second bottom. The second side wall isolates the rotor assembly and the stator assembly. An outer peripheral surface of the second side wall is provided with reinforcing ribs, and the reinforcing ribs improve the strength of the second side wall.
