Abstract:
In this drive device, a motor (80) and a control unit (10) are integrally configured. A motor frame (840) is provided to the end of the motor (80) that is toward the control unit (10) in the axial direction of the motor (80). A cover (50) has a top plate (561) and an outer cylinder (562) and is provided with at least one external connector (57, 58). At least two substrates (31, 32) are disposed in multiple stages from a first substrate (31), which is closest to the motor frame (840), to an Nth substrate (32), which is closest to the top plate (561), between the motor frame (840) and the top plate (561) and have electronic components constituting the control unit (10) mounted thereon. Inter-substrate connection components (63, 77, 78) electrically connect adjacent substrates to each other. With regard to the fastening of the first substrate (31) and the second substrate (32) to the motor frame (840), a plurality of composite fastening members (401) perform the fastening of the first substrate and the fastening of the second substrate along the same axis.
