Abstract: A housing is shaped in a bottomed tubular form. A stator is fixed to a stator receiving portion of a tubular portion of the housing at an arbitrary angle position around an axis of the tubular portion. A heat sink is fixed to a heat sink fixing portion of the tubular portion at an arbitrary angle position around the axis of the tubular portion. A control device includes a connector for electrically connecting with an external device and is configured to control energization of the stator. Each of a plurality of externally mounting portions is a part of a bottom portion of the housing and is formed integrally with the housing in one-piece. A plurality of housing positioning holes are formed at the bottom portion of the housing and are arranged at equal intervals along a circle that is concentric with the tubular portion.

Abstract: In a driver device, a controller substrate has a center part on which a rotation angle sensor is attached and an outer periphery portion which is fixed onto a heat sink. The heat sink has a cylinder part extending in an axial direction of the rotation shaft to contact the outer periphery portion of the controller substrate. The cylinder part of the heat sink is continuously formed along an entire periphery and has the same height at all portions. Such configuration provides an even deformation distribution of the cylinder part due to a temperature change, thereby reducing unevenness of heat stress distribution along a substrate plane and decreasing stress applied to the sensor, which facilitates a reduction of a detection error of the sensor.

Abstract: A motor unit is received in a first space of a motor case. A frame contacts an inner peripheral wall of the motor case and is fixed in an inside of the motor case. A cutout, which is formed in at least one of the motor case and the frame, forms a seal groove, which extends in a circumferential direction between the motor case and the frame. A cover covers the seal groove and forms a second space in an inside of the cover. A seal material is received in the seal groove and limits intrusion of liquid, such as water, from an outside of the motor case and the cover into the first space and the second space. In this way, intrusion of the liquid into the first space and the second space can be limited with the seal material provided in the single seal groove.

Abstract: A drive device includes a motor, a substrate arranged perpendicular to a motor shaft on one axial end of the motor and having a conductive connection portion, a frame body reserving a space on a substrate side, a frame member having a substrate pedestal for fixing the substrate, a cover member covering an opposite surface of the substrate relative to the frame member, and a connector having a connector terminal that extends along the axial direction and is press-fitted to the connection portion of the substrate. When the connector terminal of the connector is press-fitted to the substrate and the cover member is disposed at the same time, the number of work steps in an assembly procedure of the drive device is reduced.

Abstract: A drive apparatus includes a power module, a connector and a heat sink. The connector is used for electric connection to an external side and has a flange, which is formed on its peripheral wall. The heat sink is formed to have a module holding part for holding the power module and a fitting hole for fitting with the flange and has a connector holding part for holding a connector. The flange is formed along a first surface, which faces the connector holding part of the peripheral wall, and side surfaces, which are formed on both sides of the first surface. Thus, water droplets are prevented from entering into a control unit through a clearance between the connector and the heat sink without adding other members such as a water preventing cover.

Abstract: A drive device includes a control unit with a substrate. The control unit is disposed on an opposite side of a motor relative to an output shaft of the motor. The substrate has electronic components mounted on the substrate. A motor line connects the substrate and a winding. A frame member bears the surface-mount electronic components on a first surface of the substrate. A bearing holder holds a bearing that bears a shaft. A motor line takeout part allows the motor line to extend toward the control unit. A partition wall separates the shaft and the control unit at a radial inside position of the motor line takeout part. Such a structure prevents foreign matter from intruding into a control unit accommodating space.
