  • Publication number: 20190181724
    Abstract: A motor includes a rotor to rotate about a motor axis, and a stator radially outside of the rotor. The rotor includes a shaft extending along the motor axis, a rotor core surrounding the shaft from radially outside, a plate-shaped end plate at an axial end portion of the rotor core, and a cover portion at the axial end portion of the rotor core with the end plate intervening between the cover portion and the rotor core. The end plate includes a plate through hole extending in an axial direction, a first recessed portion extending radially inward from the plate through hole, and a second recessed portion extending radially outward from the plate through hole. The first recessed portion opens radially inward in the end plate. The first recessed portion includes an axially-facing opening covered with the rotor core. The second recessed portion includes an axially-facing opening including a covered portion covered with the cover portion, and an open portion not covered with the cover portion.
