Abstract: An electric oil pump includes a motor including a shaft, a pump driven via the shaft, and an inverter on a rear side of the motor and fixed to the motor. The motor includes a rotor, a stator, and a motor housing. The pump includes a pump rotor and a pump housing. The motor housing includes a bottomed tubular shape including a bottom portion on the inverter side, and the inverter portion includes an inverter housing that accommodates a circuit board. The inverter includes a metal base plate on a front side of the inverter housing and extends in the radial direction with respect to the central axis. The base plate is fixed to the bottom portion of the motor housing.

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 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.
