A motor includes a motor main body including a rotor and a stator, a housing that houses the motor main body, a controller that is located above the motor main body o controls rotation of the rotor, and a cover that surrounds the controller from a radially outer side. The housing includes a cover joint that is annular and surrounds the controller when viewed in an axial direction. The cover includes a cylindrical portion that surrounds the cover joint from an outside in a radial direction. The cover joint includes a contact portion that contacts a surface of the cylindrical portion in the radial direction and an adhesive joint that is bonded with the cylindrical portion via an adhesive in the radial direction. The contact portion and the adhesive joint are adjacent each other in a circumferential direction.

Motor including sealing structure between a cover and a housing

A motor includes a motor main body, a housing, a heat sink, a controller, a connector, and a cover that surrounds the controller and the connector. The heat sink includes a connector holder including an open outer side in a radial direction and holding the connector. The motor includes a ring-shaped cover joint portion that surrounds the controller and includes a stepped portion that includes a first surface and a second surface. The cover includes a cylindrical portion that faces the first surface in the radial direction. The motor includes a waterproof material that seals a portion between the cylindrical portion and the first surface or a portion between the cylindrical portion and the second surface.

Motor

A motor includes a motor body, a housing, a heat sink, a controller, a connector, and a cover. The heat sink includes two arm portions each extending radially outward. The connector is held between the two arm portions. The heat sink and the connector include a cover joint portion extending all the way around surfaces of the heat sink and the connector along a circumferential direction, is loop-shaped, and surrounds the controller, when viewed in an axial direction. The cover is joined to the cover joint portion. The connector includes a connector outside surface exposed between the two arm portions, and including circumferential end portions adjacent to the arm portions and overlapping with an imaginary line joining distal ends of the two arm portions or located radially inward of the imaginary line when viewed in the axial direction.
