  • Publication number: 20240093699
    Abstract: A motor includes a rotor rotatable in a circumferential direction around a center axis extending vertically, a stator to rotate the rotor, a lead wire connected to the stator, and a housing covering the rotor and the stator from a radially outer side. The housing includes a first housing located on a first side in an axial direction, and a second housing located on a second side in the axial direction. The first housing includes a wiring convex portion protruding toward the second side in the axial direction. The second housing includes a wiring recess that is recessed toward the second side in the axial direction and penetrates in a radial direction. The wiring convex portion is located in the wiring recess. The wiring convex portion includes a tip surface opposing the second side. The wiring recess includes a bottom surface opposing the first side.

  • Patent number: 11873840
    Abstract: A motor includes a rotor rotatable about a center axis extending vertically, a stator to rotate the rotor, and a housing covering the rotor and the stator from a radially outer side. The housing includes a first housing located on a first side in the axial direction, and a second housing located on a second side in the axial direction. The first housing includes a first opposing surface opposing the second housing in the axial direction, and a first wall portion extending from the first opposing surface to the second side in the axial direction. The second housing includes a second opposing surface opposing the first housing in the axial direction, a second wall portion extending from the second opposing surface to the first side in the axial direction, and a base portion holding the stator. The first wall portion and the second wall portion oppose each other in a radial direction.
