Rotor and motor

Abstract

To reduce a leakage flux of a permanent magnet and suppress a decrease in magnet torque. A rotor includes a rotor body rotatable about a rotation axis and permanent magnets arranged in a circumferential direction centered on the rotation axis in the rotor body and having different magnetic poles alternately in the circumferential direction. The sectional shape of the permanent magnet perpendicular to the rotation axis is a shape extending along a predetermined reference line. The permanent magnet is magnetized in a direction crossing the reference line in a section perpendicular to the rotation axis. At least one end portion of the permanent magnet in the direction of the reference line is exposed through the outer peripheral surface of the rotor body.
