Abstract
A rotor includes a cylindrical rotor core including salient pole portions protruding in a radial direction and extending along a central axis and magnetic pole portions each including a rotor magnet and alternately arranged with the salient pole portions in a circumferential direction of the rotor core on an outer circumferential surface or a radially inner side of the rotor core. The salient pole portions and the magnetic pole portions are magnetic poles of the rotor. Each of the salient pole portions includes, in a cross section perpendicular to the central axis, a salient pole tapered portion at at least one end portion in the circumferential direction, where an outer circumferential surface of the salient pole portion is linearly inclined radially inward from a center to an outer side of the salient pole portion in the circumferential direction.
