Abstract

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.
