An electric oil pump includes a motor including a motor shaft, a pump assembly including a vane pump driven by the motor to suction and discharge oil, and an inverter to drive the motor. The motor includes a rotor, a stator on a side outward from the rotor in a radial direction, and a motor housing containing the rotor and the stator. The motor housing includes a suction port through which the vane pump suctions oil from outside, and a discharge port through which the vane pump discharges oil to outside. The motor housing includes flat surface portions in a portion of an outer periphery thereof. The suction port and the discharge port are located in a first surface of side surfaces which are the flat surface portions of the motor housing and are parallel or substantially parallel to the axial direction.

Electric oil pump

An electric pump provided with a pump unit configured to discharge working oil by being rotationally driven by an electric motor includes: a drive shaft configured to transmit rotational driving force from the electric motor to a rotor of the pump unit; a rotation-detection shaft provided coaxially with the drive shaft, the rotation-detection shaft being configured to be rotated together with the rotor; and a rotation detector unit configured to detect rotation of the rotation-detection shaft. The rotation-detection shaft has: an engagement portion configured to engage with the rotor; and a detection-target portion facing the rotation detector unit, and an outer diameter of the detection-target portion is set so as to be larger than an outer diameter of the engagement portion.
