Abstract: A motor includes a drive source assembly including a first wiring, a rotation detector including a second wiring, and a motor housing. The motor housing includes a first motor housing that accommodates at least a portion of the drive source assembly, and a second motor housing that accommodates at least a portion of the rotation detector. The first motor housing includes a first penetration portion that radially penetrates the circumferential wall portion of the first motor housing and is open to one axial side, and the second motor housing includes a second penetration portion that radially penetrates the circumferential wall portion of the second motor housing and is open to another axial side. The first wiring is lead out to the outside of the first motor housing via the first penetration portion, and the second wiring is lead out to the outside of the second motor housing via the second penetration portion.

Abstract: A bus bar assembly includes a bus bar holder and bus bars each including a main line portion extending in a plane perpendicular or substantially perpendicular to a center axis in a posture in which a plate surface is oriented in an axial direction, and a connection terminal portion connected to an end portion of the main line portion. When viewed in the axial direction as a symmetry axis, the main line portion of the first U-phase bus bar and the main line portion of the second U-phase bus bar, the main line portion of the first V-phase bus bar and the main line portion of the second V-phase bus bar, and the main line portion of the first W-phase bus bar and the main line portion of the second W-phase bus bar, each have a shape line-symmetric to each other.

Abstract: A method of manufacturing of the bus bar assembly includes preparing a mold, positioning a bus bar and a shield in the mold, and molding a bus bar holder. The positioning includes inserting first positioning pins into bus bar through holes to cause the first positioning pins to hold the bus bar, providing the shield in the mold in a state where a lower surface of the shield and a distal end of the first positioning pin are in contact with each other, bringing a second positioning pin into contact with an upper surface of the shield and positioning the shield in a vertical direction, and bringing a third positioning pin extending downward from a lower surface of an upper mold into contact with an upper surface of the bus bar to position the bus bar in the vertical direction.
