Abstract

A rotor includes a rotor body rotatable about a rotation axis and magnetic pole portions arranged in the rotor body. Each magnetic pole portion includes first and second magnets, the second being inside the first in a radial direction centered on the rotation axis. The rotor body includes first and second mount holes in each of which the first and second magnets is to be respectively located. The rotor body has division walls each of which divides the second mount hole. The first mount hole is one undivided hole. When the intersection of the outer peripheral surface of the rotor body with the d-axis of each magnetic pole portion is taken as a reference point, the dimension of a portion of the first magnet positioned between the reference point and the division wall in a magnetization direction is greater than the dimension of other portions of the first magnet.
