Abstract

A canned electric motor for a fluid pump. The canned electric motor includes a static motor frame, a rotor shaft, a rotatable motor rotor which is co-rotatably connected with the rotor shaft, a static motor stator having a stator body which is directly fixed to the static motor frame, and a separating can which fluidically separates the static motor stator from the rotatable motor rotor. The separating can has a first axial support which protrudes radially from an outside of the separating can. The separating can is supported in a first axial direction by the stator body via the first axial support and in a second axial direction by the static motor frame. The first axial direction is opposite to the second axial direction.
