Abstract

A fluid pump for conveying a fluid may include an internal rotor rotatable about an axis of rotation relative to an external stator and an impeller connected to the internal rotor in a rotationally fixed manner configured to convey a fluid. The internal rotor may include a rotor receiving sleeve having a base body. The base body may include a receiving chamber configured to receive an anchor unit. The internal rotor may further include a bearing bushing penetrating the rotor receiving sleeve coaxially to the axis of rotation. The bearing bushing may be configured to receive a rotor shaft. The impeller may be directly connected to the rotor receiving sleeve in a rotationally fixed manner.
