Abstract
An automotive electric liquid pump includes a pump wheel, an EC-motor which directly drives the pump wheel, and a cover disk. The EC-motor comprises a wet motor rotor. The wet motor rotor comprises a ring-like motor rotor cavity, and a motor rotor body comprising a cylindrical rotor body section. The cylindrical rotor body section is permanently magnetized and surrounds a motor rotor cavity which is ring-like. The cover disk is arranged at a longitudinal rotor end opposite to the pump wheel. The cover disk closes the motor rotor cavity.
