Abstract
A rotor includes permanent magnets, an annular outer periphery side iron core (first core) disposed on the inner diameter side of the permanent magnets, an annular inner periphery side iron core (second core) disposed on the inner diameter side of the first core, and an insulating member insulating the first core and the second core from each other. The first core includes positioning convex portions protruding from the outer periphery toward the outer diameter side, formed in the circumferential direction and positioning the permanent magnets, and outer periphery side rotation locking concave portions being concave from the inner periphery toward the outer diameter side and formed in the circumferential direction. The positioning convex portions and the outer periphery side rotation locking concave portions are formed in positions overlapping each other when viewed in the radial direction from the central axis of the second core.
