Abstract

An electric fluid pump for a motor vehicle includes a housing composite, a pump unit, a drive motor, a rotor shaft, and a motor controller which controls the drive motor. The housing composite defines a pump space, which includes a pump rotor space wherein a pump rotor of the pump unit is arranged, and a motor space wherein the drive motor is arranged, which together comprise a common end wall. The drive motor includes a motor stator, a motor coil arrangement, and a motor rotor. The rotor shaft co-rotatably connected to the motor rotor, and is arranged through the common end wall to rotate jointly with the pump rotor. The common end wall is a mounting wall part on which at least the motor controller is arranged. The motor coil arrangement is arranged on the motor stator and is provided on a side which is opposite to the motor controller.
