Abstract

An automotive electronic flow pump includes a rotating pump wheel, a pump housing, an axial-flux motor, a static separation wall, and a motor electronics. The pump wheel has an axial fluid inlet at a wheel upstream front side and a radial fluid outlet. The pump housing defines a pumping chamber and an electronics chamber. The axial-flux motor directly drives the pump wheel and is arranged within the pumping chamber. The axial-flux motor includes a motor stator having at least one stator coil, and a motor rotor arranged at a front side of the pump wheel which co-rotates with the pump wheel. The static separation wall is arranged at a backside of the pump wheel. The static separation wall fluidically separates the pumping chamber from the electronics chamber. The motor electronics is arranged in the electronics chamber and is directly electrically connected to the at least one stator coil.
