Abstract:
An embodiment of this rotor comprises: a rotor core that extends along a central axis; and a pair of fans attached to respective end faces of the rotor core, the end faces facing both axial-direction sides of the rotor core. With regard to the fans attached to respective end faces of the rotor core, the direction in which one end face is oriented is defined as one axial side, and the direction in which the other end face is oriented is defined as the other axial side. The fans include: a plate-shaped body part having a first surface facing toward one axial side and a second surface facing toward the other axial side; and a first rib and a second rib that extend along the body part in the circumferential direction. The body part has a first through-hole and a second through-hole that are arranged side by side in the circumferential direction and that each interconnect the first and second surfaces. The first surface has a first opening section in which the first through-hole opens and a second opening section in which the second through-hole opens. The first rib is located on a rim radially outside the first opening section and projects toward the one axial side. The second rib is located on a rim radially inside the second opening section and projects radially outward.
