Abstract

An electric fluid pump may include a pump housing and an electric motor arranged in the pump housing. A rotor of the electric motor may have a rotor shaft and may be mounted in a stator of the electric motor so as to be rotatable about an axis of rotation. The pump housing may be divided into a dry region and a wet region in which the rotor may be disposed. The dry region and the wet region may be separated by a stator support piece which may at least regionally enclose the stator.
