Abstract

An electric fluid pump may include a wet section having a pump wheel and a permanently excited rotor of an electric motor arranged therein. The electric fluid pump may include a dry section having a stator of the electric motor arranged therein. A containment shell may be included configured to separate the wet section from the dry section. The dry section may include control electronics for controlling the fluid pump. The control electronics may connect in a heat-transferring manner to the containment shell and the wet section via the containment shell.
