Abstract: An electric oil pump includes a motor part having a shaft, a pump part located on a front side of the motor part and driven via the shaft, and a control part controlling the motor part. The motor part includes a rotor, a stator, and a motor housing accommodating the rotor and the stator. The pump part includes a pump rotor mounted on the shaft protruding from the motor part, and a pump housing accommodating the pump rotor. The control part includes a substrate having a surface on which a plurality of electronic components are mounted. The surface of the substrate is disposed to face the cylindrical portion of the motor housing and extends in the axial direction. The substrate has an axial length shorter than an axial length of an assembly of the motor part and the pump part and is disposed within an axial range of the assembly.

Abstract: An electric oil pump includes a motor part having a shaft, a pump part located on a front side of the motor part and driven via the shaft, and a control part which controls the motor part. The motor part includes a rotor, a stator, and a motor housing having a cylindrical portion which accommodates the rotor and the stator. The pump part includes a pump rotor, and a pump housing which accommodates the pump rotor. The control part includes a substrate having a surface on which a plurality of electronic components are mounted. The surface of the substrate is disposed to face the cylindrical portion and extends in the axial direction. A coil, which is provided on the stator, and the substrate are electrically connected via a connecting bus bar assembly. The connecting bus bar assembly is disposed between the cylindrical portion and the substrate.

Abstract: An electric oil pump includes a motor part having a shaft; a pump part that is positioned on one side of the motor part and is driven by the motor part via the shaft and discharges oil; and a control part configured to control an operation of the motor part. The motor part includes a rotor, a stator disposed to face the rotor, and a motor housing in which the rotor and the stator are accommodated. The pump part includes a pump rotor attached to the shaft and a pump housing having a housing part. The control part includes a plurality of electronic components and a board on which the electronic components are mounted. The motor housing has a cylindrical part. An end of the board is disposed at a position overlapping the cylindrical part in a direction orthogonal to a surface of the board.
