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.

Abstract: An electric coolant pump includes a pump housing, an electric motor, and a pump wheel. The pump housing includes a pumping chamber and a motor chamber. The pumping chamber includes an inlet, an outlet, and a pump volute which extends from the inlet to the outlet. The pump volute has a volute cooling sector having a radial width to axial height ratio of >1.5. A separation sidewall having a cooling section fluidically separates the motor chamber from the pumping chamber. The electric motor has a motor stator which is arranged in the motor chamber, a rotating motor rotor, and a motor electronics which is arranged in the motor chamber axially adjacent to the volute cooling sector and in a thermal contact with the cooling section. The motor electronics energizes the static motor stator. The pump wheel is arranged in the pumping chamber and is connected with the motor rotor.
