Title:
MOTOR UNIT AND ELECTRIC OIL PUMP
Document Type and Number:
WIPO Patent Application WO/2019/208076
Kind Code:
A1
Abstract:
A control unit has a first electronic component and a control substrate on which the first electronic component is mounted. A detection unit has a second electronic component and a rotation angle detection substrate on which the second electronic component is mounted. The plane of the control substrate expands in a direction perpendicular to an axial direction. The plane of the rotation angle detection substrate expands in a direction perpendicular to the axial direction. The rotation angle detection substrate is located on the other axial side of a shaft. The control substrate is located on the other axial side of the rotation angle detection substrate. The control substrate overlaps the rotation angle detection substrate in the axial direction. A connection member electrically connects the rotation angle detection substrate and the control substrate. The connection member has an extending part extending in a direction away from the rotation angle detection substrate and the control substrate.
