Abstract
An electrically driven pump includes a rotor assembly, and the rotor assembly includes a first part and a second part. The first part is integrally formed by injection molding, and includes an upper plate and vanes of an impeller, the upper plate is integrally formed with the vanes by injection molding, and each of the vanes is formed with a first connecting portion. The second part is integrally formed by injection molding, the first part and the second part are fixed by welding the first connecting portion and a second connecting portion, and in this way, the manufacturing cost of the rotor assembly is reduced, also a shaft sleeve integrally formed has a simple forming process.
